In the availability and pricing section, we have reviewed the plans and we will be upgrading to 50 or 100 million calls/month but before we do, we have a couple questions. Does the API have rate limit or throttling? Do you have additional weather forecast endpoints like hail, radar, or pollen forecast? I see in this thread https://developer.apple.com/forums/thread/795642 that air quality is not available Thanks

I'm trying to authenticate to a git host using SSH keys stored in 1Password. I have ~/.ssh/config with mode 600 set with a symlink: Host * IdentityAgent "~/.1password/agent.sock" But ssh-add -l shows no identities. If I set $SSH_AUTH_SOCK, ssh-add -l works just fine. I'd love to not have to do this, though. Why doesn't ssh-add seem to read ~/.ssh/config? The built-in version is OpenSSH_10.0p2, LibreSSL 3.3.6. I've searched fruitlessly for an answer anywhere else.

Hello, I need a little bit of help. My game keeps crashing on launch no matter what I do. I’ve tried running it in Xcode on my Mac, on my iPhone, and through TestFlight, but I get the same result every time. I’ve tried everything I could find on the internet, and nothing worked. Asking here is my last resort because I’m completely stuck. The game runs fine in Unity, but not so much in Xcode. Can someone help me figure out what I’m doing wrong?Any help would be greatly appreciated. Here is the error log I found by connecting my iPhone to my Mac. To view the logs, I used the Console in the Devices and Simulators section of Xcode. ➤ SecKeyVerifySignature failed: Error Domain=NSOSStatusErrorDomain Code=-50 "rsa_pub_crypt failed" [10:27:36.034791+0200] kernel ➤ Sandbox: [App] deny(1) sysctl-read kern.bootargs [10:27:36.043389+0200] SpringBoard ➤ Live host view super view[(null)] not matching container view ➤ Frame not updated [10:27:36.050473+0200] backboardd ➤ Cycle detected [10:27:36.100799+0200] SpringBoard ➤ Live host view super view[(null)] not matching container view [10:27:36.538361+0200] akd ➤ Error fetching keychain item - Error Domain=NSOSStatusErrorDomain Code=-25300 "no matching items found" [10:27:36.545734+0200] akd ➤ Failed to set last known MID with error (Error Domain=NSOSStatusErrorDomain Code=-25300) [10:27:36.603384+0200] rtcreportingd ➤ Gap in hierarchy: [10:27:36.604536+0200] cloudd ➤ TCP input flags=[R.] state=LAST_ACK [10:27:36.613317+0200] cloudd ➤ TCP input flags=[R] state=CLOSED [10:27:36.648449+0200] kernel ➤ 1 duplicate report for Sandbox: [App] deny(1) sysctl-read kern.bootargs [10:27:36.648484+0200] kernel ➤ Sandbox: [App] deny(1) file-test-existence /private/var/Managed Preferences/mobile/com.apple.CoreMotion.plist [10:27:36.900275+0200] CommCenter ➤ Client is not entitled for request [10:27:37.131555+0200] storekitd ➤ AMSURLSession: Session decoder failed.

I am trying to add promotional offers in my iOS App. The signature is being verified through a google cloud function. My user id, signature, and product and offerIds return perfect. Promotional offer appears in the payment sheet as well. When applying for payment, the "ding" sound comes as well. But then I get the UIAlert with Unable to Purchase Contact developer. Error code in logs is 3903

My application targets iOS 15+. Attempting to build and run it on my iPhone SE (orphaned at iOS 15.6) results in "Failed to prepare the device for development." I'm building with Xcode 15.2. What is the expected procedure here?

I have a Apple Developer accounts for development purposes only and that is also used for testing builds via TestFlight. Is the Age Ratings Responses updates due by the end of January 2026 still required even to send builds to TestFlight?

Subject: Assistance Needed with Enabling Speech Recognition Entitlement for iOS App Hi everyone, I’m seeking guidance regarding the Speech Recognition entitlement for my iOS app using Capacitor. Our App and we submitted a request to Apple Developer Support four days ago, but have not yet received a response. 🧩 Summary of the issue: Our app uses the Capacitor speech recognition plugin (@capacitor-community/speech-recognition) to listen for native voice input on iOS. We have added both of the required keys in Info.plist: NSSpeechRecognitionUsageDescription NSMicrophoneUsageDescription We previously had a duplicate microphone key, which caused the system to silently skip the permission request. After removing the duplicate, we did briefly see the microphone permission prompt appear. However, in our most recent builds, the app launches without any prompts, even on a fresh install. The plugin reports: available = true permissionStatus = granted Despite this, no speech input is ever received, and the listener returns nothing. We believe the app is functioning correctly at a code level (plugin loads, no errors, correct Info.plist), but suspect the missing Speech Recognition entitlement is blocking actual access to the speech system. 🔎 What we need help with: How can we confirm whether the Speech Recognition entitlement is enabled for our App ID? If it’s not enabled, is there a way to escalate or re-submit the request? Our app is currently stuck until this entitlement is granted. Thank you for your time and any guidance you can offer!

Hi, I am using Installer JS in Distrtibution file which is created using productbuild command. I am trying to read the installed version of app from the plist file present in the /var/db/receipts folder. It gives the following warning. If I enable the flag , notarization will fail. FJS: Package Authoring Error: access to path "/var/db/receipts/com.xxx.xxx.plist" requires Following is the function I have used to read the installed version. system.files.plistAtPath() I have also tried the following function to read the version from .app file. system.files.bundleAtPath Both the functions give the warning. Is there are a way to avoid this warning or a better way to read the installed version? Regards Prema Kumar

I have an issue when i use external tester with a public link and emails. Test fly is well installed but when i have to open the app, it just charge as seen in the screen.

I am developing a simple watch app and I use my personal watch for development with Xcode. Personal watch is series 10 gps only. I have two other watches that I want to use for testing the app, but not needing them to be connected to Xcode. The test watches have cellular option, and I need a cell plan per watch because the watches need to be standalone, not counting initial setup. To get the standalone cell plan the watches need to be configured using AWFK. Here is what I have tried/current issues. I switch between all three watches on my phone using the watch app. Originally tried to put test watches in developer mode, thinking I would connect to Xcode, developer mode is not available when watch is setup using AWFK. Pushed the watch app to apple connect, setup TestFlight group, added the test users and my phone user, accepted invites TestFlight is installed on my phone, I see the testflight setup for the watch app I set a test watch using watch app on the phone, run install for the test app from TestFlight on the phone, spinner moves for awhile then goes back to Install. I am not able to get the watch app installed on the test watches from the phone. Is what I am attempting to do supported? I haven't found much specific documentation on this. If I pair the test watches as regular watches, set them to developer mode, can I pair them again as AWFK and will developer mode survive the switch? Or is there something really simple that I'm overlooking? Appreciate any help that can be extended.

Hello, I've encountered unexpected behavior related to version information in our app logs, and I'd like to ask for some advice. We reviewed logs collected from a user running our app (currently available on the App Store). The logs are designed to include both the build number and the app version. Based on the build number in the logs, we believe the installed app version on the user's device is 1.0.3. However, the app version recorded in the logs is 1.1.5, which is the latest version currently available on the App Store. In our project, we set the app version using the MARKETING_VERSION environment variable. This value is configured via XcodeGen, and we define it in a YAML file. Under normal circumstances, the value defined in the YAML file (MARKETING_VERSION = 1.0.3) should be embedded in the app and reflected in the logs. But in this case, the version from the current App Store release (1.1.5) appears instead, which was unexpected. We'd like to know what might cause this behavior, and if there are any known factors that could lead to this. Also, is it possible that MARKETING_VERSION might somehow dynamically reflect the version currently available on the App Store? YAML: info.plist:

This posts collects together a bunch of information about the symbols found in a Mach-O file. It assumes the terminology defined in An Apple Library Primer. If you’re unfamiliar with a term used here, look there for the definition. If you have any questions or comments about this, start a new thread in the Developer Tools & Services > General topic area and tag it with Linker. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Understanding Mach-O Symbols Every Mach-O file has a symbol table. This symbol table has many different uses: During development, it’s written by the compiler. And both read and written by the linker. And various other tools. During execution, it’s read by the dynamic linker. And also by various APIs, most notably dlsym. The symbol table is an array of entries. The format of each entry is very simple, but they have been used and combined in various creative ways to achieve a wide range of goals. For example: In a Mach-O object file, there’s an entry for each symbol exported to the linker. In a Mach-O image, there’s an entry for each symbol exported to the dynamic linker. And an entry for each symbol imported from dynamic libraries. Some entries hold information used by the debugger. See Debug Symbols, below. Examining the Symbol Table There are numerous tools to view and manipulate the symbol table, including nm, dyld_info, symbols, strip, and nmedit. Each of these has its own man page. A good place to start is nm: % nm Products/Debug/TestSymTab U ___stdoutp 0000000100000000 T __mh_execute_header U _fprintf U _getpid 0000000100003f44 T _main 0000000100008000 d _tDefault 0000000100003ecc T _test 0000000100003f04 t _testHelper Note In the examples in this post, TestSymTab is a Mach-O executable that’s formed by linking two Mach-O object files, main.o and TestCore.o. There are three columns here, and the second is the most important. It’s a single letter indicating the type of the entry. For example, T is a code symbol (in Unix parlance, code is in the text segment), D is a data symbol, and so on. An uppercase letter indicates that the symbol is visible to the linker; a lowercase letter indicates that it’s internal. An undefined (U) symbol has two potential meanings: In a Mach-O image, the symbol is typically imported from a specific dynamic library. The dynamic linker connects this import to the corresponding exported symbol of the dynamic library at load time. In a Mach-O object file, the symbol is undefined. In most cases the linker will try to resolve this symbol at link time. Note The above is a bit vague because there are numerous edge cases in how the system handles undefined symbols. For more on this, see Undefined Symbols, below. The first column in the nm output is the address associated with the entry, or blank if an address is not relevant for this type of entry. For a Mach-O image, this address is based on the load address, so the actual address at runtime is offset by the slide. See An Apple Library Primer for more about those concepts. The third column is the name for this entry. These names have a leading underscore because that’s the standard name mangling for C. See An Apple Library Primer for more about name mangling. The nm tool has a lot of formatting options. The ones I use the most are: -m — This prints more information about each symbol table entry. For example, if a symbol is imported from a dynamic library, this prints the library name. For a concrete example, see A Deeper Examination below. -a — This prints all the entries, including debug symbols. We’ll come back to that in the Debug Symbols section, below. -p — By default nm sorts entries by their address. This disables that sort, causing nm to print the entries in the order in which they occur in the symbol table. -x — This outputs entries in a raw format, which is great when you’re trying to understand what’s really going on. See Raw Symbol Information, below, for an example of this. A Deeper Examination To get more information about each symbol table, run nm with the -m option: % nm -m Products/Debug/TestSymTab (undefined) external ___stdoutp (from libSystem) 0000000100000000 (__TEXT,__text) [referenced dynamically] external __mh_execute_header (undefined) external _fprintf (from libSystem) (undefined) external _getpid (from libSystem) 0000000100003f44 (__TEXT,__text) external _main 0000000100008000 (__DATA,__data) non-external _tDefault 0000000100003ecc (__TEXT,__text) external _test 0000000100003f04 (__TEXT,__text) non-external _testHelper This contains a world of extra information about each entry. For example: You no longer have to remember cryptic single letter codes. Instead of U, you get undefined. If the symbol is imported from a dynamic library, it gives the name of that dynamic library. Here we see that _fprintf is imported from the libSystem library. It surfaces additional, more obscure information. For example, the referenced dynamically flag is a flag used by the linker to indicate that a symbol is… well… referenced dynamically, and thus shouldn’t be dead stripped. Undefined Symbols Mach-O’s handling of undefined symbols is quite complex. To start, you need to draw a distinction between the linker (aka the static linker) and the dynamic linker. Undefined Symbols at Link Time The linker takes a set of files as its input and produces a single file as its output. The input files can be Mach-O images or dynamic libraries [1]. The output file is typically a Mach-O image [2]. The goal of the linker is to merge the object files, resolving any undefined symbols used by those object files, and create the Mach-O image. There are two standard ways to resolve an undefined symbol: To a symbol exported by another Mach-O object file To a symbol exported by a dynamic library In the first case, the undefined symbol disappears in a puff of linker magic. In the second case, it records that the generated Mach-O image depends on that dynamic library [3] and adds a symbol table entry for that specific symbol. That entry is also shown as undefined, but it now indicates the library that the symbol is being imported from. This is the core of the two-level namespace. A Mach-O image that imports a symbol records both the symbol name and the library that exports the symbol. The above describes the standard ways used by the linker to resolve symbols. However, there are many subtleties here. The most radical is the flat namespace. That’s out of scope for this post, because it’s a really bad option for the vast majority of products. However, if you’re curious, the ld man page has some info about how symbol resolution works in that case. A more interesting case is the -undefined dynamic_lookup option. This represents a halfway house between the two-level namespace and the flat namespace. When you link a Mach-O image with this option, the linker resolves any undefined symbols by adding a dynamic lookup undefined entry to the symbol table. At load time, the dynamic linker attempts to resolve that symbol by searching all loaded images. This is useful if your software works on other Unix-y platforms, where a flat namespace is the norm. It can simplify your build system without going all the way to the flat namespace. Of course, if you use this facility and there are multiple libraries that export that symbol, you might be in for a surprise! [1] These days it’s more common for the build system to pass a stub library (.tbd) to the linker. The effect is much the same as passing in a dynamic library. In this discussion I’m sticking with the old mechanism, so just assume that I mean dynamic library or stub library. If you’re unfamiliar with the concept of a stub library, see An Apple Library Primer. [2] The linker can also merge the object files together into a single object file, but that’s relatively uncommon operation. For more on that, see the discussion of the -r option in the ld man page. [3] It adds an LC_LOAD_DYLIB load command with the install name from the dynamic library. See Dynamic Library Identification for more on that. Undefined Symbols at Load Time When you load a Mach-O image the dynamic linker is responsible for finding all the libraries it depends on, loading them, and connecting your imports to their exports. In the typical case the undefined entry in your symbol table records the symbol name and the library that exports the symbol. This allows the dynamic linker to quickly and unambiguously find the correct symbol. However, if the entry is marked as dynamic lookup [1], the dynamic linker will search all loaded images for the symbol and connect your library to the first one it finds. If the dynamic linker is unable to find a symbol, its default behaviour is to fail the load of the Mach-O image. This changes if the symbol is a weak reference. In that case, the dynamic linking continues to load the image but sets the address of the symbol to NULL. See Weak vs Weak vs Weak, below, for more about this. [1] In this case nm shows the library name as dynamically looked up. Weak vs Weak vs Weak Mach-O supports two different types of weak symbols: Weak references (aka weak imports) Weak definitions IMPORTANT If you use the term weak without qualification, the meaning depends on your audience. App developers tend to assume that you mean a weak reference whereas folks with a C++ background tend to assume that you mean a weak definition. It’s best to be specific. Weak References Weak references support the availability mechanism on Apple platforms. Most developers build their apps with the latest SDK and specify a deployment target, that is, the oldest OS version on which their app runs. Within the SDK, each declaration is annotated with the OS version that introduced that symbol [1]. If the app uses a symbol introduced later than its deployment target, the compiler flags that import as a weak reference. The app is then responsible for not using the symbol if it’s run on an OS release where it’s not available. For example, consider this snippet: #include <xpc/xpc.h> void testWeakReference(void) { printf("%p\n", xpc_listener_set_peer_code_signing_requirement); } The xpc_listener_set_peer_code_signing_requirement function is declared like so: API_AVAILABLE(macos(14.4)) … int xpc_listener_set_peer_code_signing_requirement(…); The API_AVAILABLE macro indicates that the symbol was introduced in macOS 14.4. If you build this code with the deployment target set to macOS 13, the symbol is marked as a weak reference: % nm -m Products/Debug/TestWeakRefC … (undefined) weak external _xpc_listener_set_peer_code_signing_requirement (from libSystem) If you run the above program on macOS 13, it’ll print NULL (actually 0x0). Without support for weak references, the dynamic linker on macOS 13 would fail to load the program because the _xpc_listener_set_peer_code_signing_requirement symbol is unavailable. [1] In practice most of the SDK’s declarations don’t have availability annotations because they were introduced before the minimum deployment target supported by that SDK. Weak definitions Weak references are about imports. Weak definitions are about exports. A weak definition allows you to export a symbol from multiple images. The dynamic linker coalesces these symbol definitions. Specifically: The first time it loads a library with a given weak definition, the dynamic linker makes it the primary. It registers that definition such that all references to the symbol resolve to it. This registration occurs in a namespace dedicated to weak definitions. That namespace is flat. Any subsequent definitions of that symbol are ignored. Weak definitions are weird, but they’re necessary to support C++’s One Definition Rule in a dynamically linked environment. IMPORTANT Weak definitions are not just weird, but also inefficient. Avoid them where you can. To flush out any unexpected weak definitions, pass the -warn_weak_exports option to the static linker. The easiest way to create a weak definition is with the weak attribute: __attribute__((weak)) void testWeakDefinition(void) { } IMPORTANT The C++ compiler can generate weak definitions without weak ever appearing in your code. This shows up in nm like so: % nm -m Products/Debug/TestWeakDefC … 0000000100003f40 (__TEXT,__text) weak external _testWeakDefinition … The output is quite subtle. A symbol flagged as weak external is either a weak reference or a weak definition depending on whether it’s undefined or not. For clarity, use dyld_info instead: % dyld_info -imports -exports Products/Debug/TestWeakRefC Products/Debug/TestWeakDefC [arm64]: … -imports: … 0x0001 _xpc_listener_set_peer_code_signing_requirement [weak-import] (from libSystem) % dyld_info -imports -exports Products/Debug/TestWeakDefC Products/Debug/TestWeakDefC [arm64]: -exports: offset symbol … 0x00003F40 _testWeakDefinition [weak-def] … … Here, weak-import indicates a weak reference and weak-def a weak definition. Weak Library There’s one final confusing use of the term weak, that is, weak libraries. A Mach-O image includes a list of imported libraries and a list of symbols along with the libraries they’re imported from. If an image references a library that’s not present, the dynamic linker will fail to load the library even if all the symbols it references in that library are weak references. To get around this you need to mark the library itself as weak. If you’re using Xcode it will often do this for your automatically. If it doesn’t, mark the library as optional in the Link Binary with Libraries build phase. Use otool to see whether a library is required or optional. For example, this shows an optional library: % otool -L Products/Debug/TestWeakRefC Products/Debug/TestWeakRefC: /usr/lib/libEndpointSecurity.dylib (… 511.60.5, weak) … In the non-optional case, there’s no weak indicator: % otool -L Products/Debug/TestWeakRefC Products/Debug/TestWeakRefC: /usr/lib/libEndpointSecurity.dylib (… 511.60.5) … Debug Symbols or Why the DWARF still stabs. (-: Historically, all debug information was stored in symbol table entries, using a format knows as stabs. This format is now obsolete, having been largely replaced by DWARF. However, stabs symbols are still used for some specific roles. Note See <mach-o/stab.h> and the stab man page for more about stabs on Apple platforms. See stabs and DWARF for general information about these formats. In DWARF, debug symbols aren’t stored in the symbol table. Rather, debug information is stored in various __DWARF sections. For example: % otool -l Intermediates.noindex/TestSymTab.build/Debug/TestSymTab.build/Objects-normal/arm64/TestCore.o | grep __DWARF -B 1 sectname __debug_abbrev segname __DWARF … The compiler inserts this debug information into the Mach-O object file that it creates. Eventually this Mach-O object file is linked into a Mach-O image. At that point one of two things happens, depending on the Debug Information Format build setting. During day-to-day development, set Debug Information Format to DWARF. When the linker creates a Mach-O image from a bunch of Mach-O object files, it doesn’t do anything with the DWARF information in those objects. Rather, it records references to the source objects files into the final image. This is super quick. When you debug that Mach-O image, the debugger finds those references and uses them to locate the DWARF information in the original Mach-O object files. Each reference is stored in a stabs OSO symbol table entry. To see them, run nm with the -a option: % nm -a Products/Debug/TestSymTab … 0000000000000000 - 00 0001 OSO …/Intermediates.noindex/TestSymTab.build/Debug/TestSymTab.build/Objects-normal/arm64/TestCore.o 0000000000000000 - 00 0001 OSO …/Intermediates.noindex/TestSymTab.build/Debug/TestSymTab.build/Objects-normal/arm64/main.o … Given the above, the debugger knows to look for DWARF information in TestCore.o and main.o. And notably, the executable does not contain any DWARF sections: % otool -l Products/Debug/TestSymTab | grep __DWARF -B 1 % When you build your app for distribution, set Debug Information Format to DWARF with dSYM File. The executable now contains no DWARF information: % otool -l Products/Release/TestSymTab | grep __DWARF -B 1 % Xcode runs dsymutil tool to collect the DWARF information, organise it, and export a .dSYM file. This is actually a document package, within which is a Mach-O dSYM companion file: % find Products/Release/TestSymTab.dSYM Products/Release/TestSymTab.dSYM Products/Release/TestSymTab.dSYM/Contents … Products/Release/TestSymTab.dSYM/Contents/Resources/DWARF Products/Release/TestSymTab.dSYM/Contents/Resources/DWARF/TestSymTab … % file Products/Release/TestSymTab.dSYM/Contents/Resources/DWARF/TestSymTab Products/Release/TestSymTab.dSYM/Contents/Resources/DWARF/TestSymTab: Mach-O 64-bit dSYM companion file arm64 That file contains a copy of the the DWARF information from all the original Mach-O object files, optimised for use by the debugger: % otool -l Products/Release/TestSymTab.dSYM/Contents/Resources/DWARF/TestSymTab | grep __DWARF -B 1 … sectname __debug_line segname __DWARF … Raw Symbol Information As described above, each Mach-O file has a symbol table that’s an array of symbol table entries. The structure of each entry is defined by the declarations in <mach-o/nlist.h> [1]. While there is an nlist man page, the best documentation for this format is the the comments in the header itself. Note The terms nlist stands for name list and dates back to truly ancient versions of Unix. Each entry is represented by an nlist_64 structure (nlist for 32-bit Mach-O files) with five fields: n_strx ‘points’ to the string for this entry. n_type encodes the entry type. This is actually split up into four subfields, as discussed below. n_sect is the section number for this entry. n_desc is additional information. n_value is the address of the symbol. The four fields within n_type are N_STAB (3 bits), N_PEXT (1 bit), N_TYPE (3 bits), and N_EXT (1 bit). To see these raw values, run nm with the -x option: % nm -a -x Products/Debug/TestSymTab … 0000000000000000 01 00 0300 00000036 _getpid 0000000100003f44 24 01 0000 00000016 _main 0000000100003f44 0f 01 0000 00000016 _main … This prints a column for n_value, n_type, n_sect, n_desc, and n_strx. The last column is the string you get when you follow the ‘pointer’ in n_strx. The mechanism used to encode all the necessary info into these fields is both complex and arcane. For the details, see the comments in <mach-o/nlist.h> and <mach-o/stab.h>. However, just to give you a taste: The entry for getpid has an n_type field with just the N_EXT flag set, indicating that this is an external symbol. The n_sect field is 0, indicating a text symbol. And n_desc is 0x0300, with the top byte indicating that the symbol is imported from the third dynamic library. The first entry for _main has an n_type field set to N_FUN, indicating a stabs function symbol. The n_desc field is the line number, that is, line 22. The second entry for _main has an n_type field with N_TYPE set to N_SECT and the N_EXT flag set, indicating a symbol exported from a section. In this case the section number is 1, that is, the text section. [1] There is also an <nlist.h> header that defines an API that returns the symbol table. The difference between <nlist.h> and <mach-o/nlist.h> is that the former defines an API whereas the latter defines the Mach-O on-disk format. Don’t include both; that won’t end well!

For the Linux version of my application which is written in C++ using Qt, I display the CHM format help files with this code: QString helpFile{ QCoreApplication::applicationDirPath() + "/Help/" + tr("DeepSkyStacker Help.chm","IDS_HELPFILE") }; QString program{ "kchmviewer" }; QStringList arguments{ "-token", "com.github.deepskystacker", helpFile }; helpProcess->startDetached(program, arguments); (helpProcess is a pointer to a QProcess object) The -token com.github.deepskystackerpart of that ensures that only a single instance of the viewer is used for any code that uses that invocation. Are there any chm file viewers for macOS that are capable of that sort of trick? The ones I've found on the App Store give minimal information and appear to be very simple minded tools that are not not intended for integration into an application as above. I know that MacPorts offers ports of kchmviewer but I'd prefer not to use either that or HomeBrew ... David

I would like to know if macOS DEXT supports the following networking features: Tx/Rx Multiqueue, RSS, RSC, NS/ARP offload, PTP or packet timestamping and TSN. I couldn't find relevant documentation for these features in the Apple Developer Documentation. If they are supported, could you let me know which features are supported and how to find the corresponding official Apple documentation? Thanks

On macOS, I get a system popup when running UI tests in GitHub saying: “bash” is requesting to bypass the system private window picker and directly access your screen and audio. How can I prevent these login and screen access popups from appearing during automated UI tests? Is there an official setup or configuration for running IntelliJ UI tests in CI environments (macOS, Linux, Windows) to avoid such dialogs? My builds run in GitHub Actions VMs, so I can’t manually grant these permissions, and they block the tests.

I’m developing an app that uses Family Controls to block other apps. I’ve already received approval from Apple for the entitlement, and everything works perfectly when I run the app from Xcode on a physical device. However, when I upload the same build to TestFlight, the app installs and runs, but the Family Controls functionality doesn’t work — it seems like the entitlement isn’t being applied in the TestFlight version. So I’d like to ask: 👉 Do Family Controls entitlements work automatically on TestFlight builds, or is there any additional step required to enable them?

I'm calling this command to export archive: xcodebuild -exportArchive -archivePath .build/XYZ.xcarchive -exportPath .build/XYZ.ipa -exportOptionsPlist Authenticator/ExportOptions.plist -quiet -allowProvisioningUpdates Here is my exportOptions file content &lt;!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"&gt; &lt;plist version="1.0"&gt; &lt;dict&gt; &lt;key&gt;method&lt;/key&gt; &lt;string&gt;app-store-connect&lt;/string&gt; &lt;key&gt;signingStyle&lt;/key&gt; &lt;string&gt;automatic&lt;/string&gt; &lt;key&gt;teamID&lt;/key&gt; &lt;string&gt;ABCD&lt;/string&gt; &lt;/dict&gt; &lt;/plist&gt; Most of the time this command fail with this error: error: exportArchive No Accounts error: exportArchive No signing certificate "iOS Distribution" found What we found is that our Apple ID just disappear from Xcode and we need to add it again manually. So there are two questions here: Why Apple ID account dissapears and how I can fix this? Is there an option to not use Apple ID account in Xcode and for example to use -authenticationKeyID flags of xcodebuild? Just to mention this happens only on our CI machine and not locally.

We are experiencing an issue where our app gets stuck during launch. The splash screen appears for some time, and then the app either becomes unresponsive or closes unexpectedly. However, there are no crash logs captured in Xcode or Firebase Crashlytics, indicating that the app is not crashing but rather being terminated. This issue is preventing affected users from properly launching the app. Additionally, some users have reported occasional lag and slow performance when using the app. The issue occurs only for a specific subset of users and appears to be related to other Electronic Logging Device (ELD) apps running in the background. When these apps are active, our app struggles to launch and sometimes becomes unresponsive. We suspect that this behavior could be related to system resource allocation, such as high memory consumption by background apps, which might be affecting our app's ability to launch correctly. However, we have been unable to reproduce the issue on our end despite multiple attempts. Actions Performed During App Launch: Firebase configuration API requests, including: Fetching account details Registering the FCM token with the server Asynchronous background requests to fetch POI details Creating a local database and storing POI data in local storage We would like guidance from Apple regarding potential causes and debugging strategies, especially in scenarios where the app does not produce crash logs but still fails to launch properly. Any insights into memory management, conflicts with background applications, or system resource constraints would be highly appreciated. Steps to Reproduce: Install and launch the app on an affected device. Observe that the app gets stuck on the launch screen. After some time, the app terminates unexpectedly. Issue is inconsistent and occurs only for certain users. Presence of other ELD apps running in the background appears to influence the issue.

I am integrating On Demand Resources into my Unity game. The resources install without any problems if the internet connection is stable: all resources are installed. While testing various scenarios without an internet connection, I encountered the following problem: if I turn off the internet during installation, I don't get any error messages, but if I turn the internet back on, the download no longer continues (and I still don't get an error). If I reopen the application with a stable internet connection, the download will always be at 0%.

Hi, I requested the https://itunes.apple.com/lookup?id=6482849843&country=us for getting the information of Goods puzzle sort challange , but the screenshotUrls in the response was empty. Is iTunes search API has issue with getting the screenshot urls ? Is there any plan to update it ?
