I'm trying to update the icon of my app for watchOS 26, and I'm having troubles providing both a layered Liquid Glass icon for watchOS 26 users and a pre-rendered bitmap icon (in various sizes) for watchOS 11 and older users. Whatever I do; I either get a blurry, scaled-down watchOS 26 icon on watchOS 11; or watchOS 11's bitmap icons on watchOS 26. While I could get the wanted result on macOS 26 and iOS 26, I simply can't get an equivalent result with watchOS 26.

I downloaded the Xcode Beta 3 on my MacBook Pro M4 Base today and tested out some iOS26 mechanics of my app. And when I came back to my main Xcode to continue developing in iOS18, I couldn't build my app. I went to Product > Destination > Manage run destinations and then tried to create a simulator with iOS18 but it didn't show up, only choice that's showing up was iOS26. I tried deleting iOS18 platform and downloading it again but it didn't solve, I tried deleting Xcode Beta but it didn't solve the problem either. I deleted Runtimes folder, it didn't solve too. I can not create a simulator of iOS18 or below too, the error says "The iOS 18.5 simulator runtime is not available. Try reinstalling Xcode or the simulator runtime." How can I fix this problem?

I received the attached crash report. The problem is that the crash report does not contain the abort reason - it appears to be thrown in the GCD library with no additional information. Is it a possible deadlock? 2023-02-15_02-40-23.0077_+0100-94015bd052c4005658221a5e6279f28a75b9e92c.crash Any ideas?

Hello, I am facing a recurring issue with Xcode iOS simulator (preview). I want to preview a SwiftUI for iOS in Xcode, but the Simulator app fails to boot up. I receive the following error in Xcode: Cannot Preview in this file. Simulator was shutdown during an update. I have tried the following: Completely uninstalling XCode and deleting all developer data, then reinstalling everthing again. Shutdown and restart Deleting all developer data, deleting XCode cache Reinstalling iOS Simulator runtimes and reconfiguration of simulators. Tested using different simulator and runtime versions. "xcrun simctl --set previews delete al" My reported issues: FB20987522 FB20485454 Thank you Best regards, Jens

When I update the macOS from 15.5 to 15.6, Preview error. 1、I try remove simulator cache， sdk 2、remove Xcode build cache 3、reinstall Xcode 4、try with this method https://byby.dev/uninstall-xcode#:%7E:text=Delete%20old%20simulators%20and%20devices,moving%20them%20to%20the%20Trash but all failed swiftui log.txt

Hi everyone, I recently updated to Xcode 26.0 and noticed that the “Extract Subview” refactoring option seems to be missing. Now, in Xcode 26, the only options I see under Editor -> Refactor -> are: Extract to Selection File Extract to Method Extract to Variable Extract All Occurrences But there’s no Extract Subview as there was before. Was Extract Subview intentionally removed in Xcode 26? Or is it hidden behind a new menu location or renamed?

I have a very annoying problem when I try to distribute my app to the App Store. Organizer does not recognise the project as an app I think. Xcode version is 16.2 but I have tries in 15.4.

I'm working on a large multi-platform iOS project (iOS, iPadOS, watchOS, tvOS, visionOS) and have successfully migrated from legacy .strings files to modern String Catalogs (.xcstrings). However, I'm unable to export localizations using xcodebuild -exportLocalizations due to cross-platform framework dependency issues. (Note: I did have AI help me write this question, so apologies in advance for any errors) Project Structure Main iOS/iPad app with multiple extensions watchOS companion app tvOS app visionOS app 49 .xcstrings files successfully migrated across all targets Uses Swift Package Manager for modularization The Problem When attempting to export localizations using xcodebuild -exportLocalizations, the build fails because it tries to build all targets across all platforms, including watchOS targets that depend on third-party xcframeworks that don't include watchOS slices: xcodebuild -exportLocalizations \ -project MyProject.xcodeproj \ -scheme MyApp \ -localizationPath ./export \ -configuration Debug Error: error: While building for watchOS, no library for this platform was found in 'Frameworks/<incompatible>.xcframework'. (in target 'Target') These frameworks cannot be modified to add watchOS support (third-party/legacy dependencies). What Works vs. What Doesn't Works: Building the iOS app through Xcode GUI Fails: Exporting localizations through Xcode GUI (Product → Export Localizations...) Fails: xcodebuild -exportLocalizations with any combination of flags Attempted Solutions (All Failed) Platform-specific destination: xcodebuild -exportLocalizations -destination "generic/platform=iOS" ... SDK constraint: xcodebuild -exportLocalizations -sdk iphoneos ... Excluding architectures: xcodebuild -exportLocalizations EXCLUDED_ARCHS="armv7k arm64_32" ... Build first, then export: xcodebuild build -scheme MyApp -sdk iphoneos && \ xcodebuild -exportLocalizations ... All approaches still attempt to build watchOS targets despite platform constraints. Observations The -exportLocalizations flag appears to ignore -destination and -sdk flags It seems to scan and build ALL schemes/targets in the project regardless of constraints Regular builds (xcodebuild build) work fine with platform constraints Current Workaround I created a Python script that parses .xcstrings JSON files directly and generates XLIFF output, which works but feels like it's bypassing Apple's intended workflow. Questions for Apple Is there a way to limit xcodebuild -exportLocalizations to specific platforms? The documentation doesn't mention any flags for this, and -destination/-sdk appear to be ignored. Why does -exportLocalizations require building ALL targets across ALL platforms? Both the Xcode GUI (Product → Export Localizations) and xcodebuild -exportLocalizations fail with identical build errors, suggesting this is by design. Is there a reason localization export can't be limited to buildable targets? Is the intended workflow to have ALL targets buildable across ALL platforms before exporting localizations? This seems impractical for multi-platform projects with platform-specific dependencies. Are there any build settings or configuration options that can exclude specific targets/platforms from the localization export scan? Is directly parsing .xcstrings files and generating XLIFF an acceptable alternative, or does this miss important metadata that -exportLocalizations would include? Environment Xcode 16.x / 26.x (reproduces on both) macOS Tahoe Project uses String Catalogs (.xcstrings) format Mixed SPM packages and traditional target structure Any guidance on the correct approach for multi-platform localization export would be greatly appreciated. Is this a known limitation, or is there a recommended pattern I'm missing?

Following an unexpected error message while working in Xcode, the project file xcodeproj is no longer synced in iCloud Drive. The Finder shows a cloud icon with a ! and an error message : (NSFileProviderErrorDomain error -2005.) If the local file is zipped, and unzipped elsewhere on iCloud Drive, then the unzipped file can still not be iCloud Synced. Restoring the file from a Time Machine archive does not solve the issue. Apple Care Support finds that iCloud Drive is working fine except for this xcodeproj file and says the issue is Xcode related.

I am at a loss as to why, since the latest update, that my preview pane is no longer working. May i have some assistance on the matter? Thank you in advance! 😀✌️

Good day! When your project have total 887 or more SPM local targets and then you try to build it, xcodebuild will be crash.

I use spm manage swift package, now i want my macos app support arm64e,so i add arm64e in Build Srtting -> Architectures. but i got error Could not find module 'SwiftyJSON' for target 'arm64e-apple-macos'; found: arm64-apple-macos, x86_64-apple-macos Apparently, if no limit in Package.swift, SPM will only compile versions for x86 and ARM64 architectures by default. now, how should I configure SPM to compile the arm64e version? thanks

I have an orphaned asset folder taking up 9.13GB located at: /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime/c0d3fd05106683ba0b3680d4d1afec65f098d700.asset It contains SimulatorRuntimeAsset version 18.5 (Build 22F77). Active Version: My current Xcode setup is using version 26.2 (Build 23C54). I checked the plist files in the directory and found what seems to be the cause of the issue: The "Never Collected" Flag: The Info.plist inside the orphaned asset folder explicitly sets the garbage collection behavior to "NeverCollected": <key>__AssetDefaultGarbageCollectionBehavior</key> <string>NeverCollected</string> The Catalog Mismatch: The master catalog file (com_apple_MobileAsset_iOSSimulatorRuntime.xml) in the parent directory only lists the new version (26.2). Because the old version (18.5) is missing from this XML, Xcode and mobileassetd seem to have lost track of it entirely. What I Have Tried (All Failed) Xcode Components: The version 18.5 does not appear in Settings -> Components, so I cannot delete it via the GUI. Simctl: xcrun simctl list runtimes does not list this version. Running xcrun simctl runtime delete 22F77 fails with: "No runtime disk images or bundles found matching '22F77'." Manual Deletion: sudo rm -rf [path] fails with "Operation not permitted", presumably because /System/Library/AssetsV2 is SIP-protected. Third-party Tools: Apps like DevCleaner do not detect this runtime (likely because they only scan ~/Library or /Library, not /System/Library). Has anyone found a way to force the system (perhaps via mobileassetd or a specific xcrun flag) to re-evaluate this folder and respect a deletion request? I am trying to avoid booting into Recovery Mode just to delete a cache file. Any insights on how AssetsV2 handles these "orphaned" files would be appreciated.

I want to use a ci_script to change the CI_BUILD_NUMBER to a new value. But in XCODE CLOUD there seems to be no programmatic way to change it?

I am having issues loading my model from a Swift Package with the following structure: | Package.swift | Sources | - | SamplePackage | - | - Core | - | - | - SamplePackageDataStack.swift | - | - | - DataModel.xcdatamodeld | - | - | - | - Model.xcdatamodel ( <- is this new? ) As mentioned, I am not required to list the xcdatamodeld as a resource in my Package manifest.

Hi, I am in the last step "preparing for submission" and everything excepts "age rating" is fine. How can I fix this? I have two apps and on neither i can edit "age rating" :(

I've created a new project in Xcode. I'm running the Xcode 16.4 and MacOS 15.5. I'm trying to run my barebones project on my iPhone 16 (I'm just getting started). I turned on developer mode on my iPhone and went through the whole process. But in the Signing & Capabilities of my project under status I see two errors... There is a problem with the request entity A device with number 'XXXX8801C' already exists on this team. Provisioning profile "iOS Team Provisioning Profile: [MyBundleID]" doesn't include the currently selected device "My iPhone" (identifier XXXX8801C). I noticed in the devices on the developer portal that my device is showing as "Processing." I feel ike it's stuck. But I can't figure out how to clear it all out and try again. It's been 24 hours since this error came up. I've tried to clear trusted computers on the iPhone. I've deleted the "Derived Data" folder. I've removed my developer account from Xcode and added it again. I've restarted both my Mac and my iPhone multiple times. I've noticed it asked to authorize my computer twice. When I clear the authorized computers and then plug the phone back in it asks twice again. So I'm not sure if this is the issue? No idea why it asks twice but I'm only ever able to respond to the second request as the first request gets blocked in the UI by the second requests if that makes sense? I'm also not able to turn off developer mode on my iPhone. The switch isn't there as the docs state it should be. So again, I feel like this is the phone and the developer portal stuck causing the problem. Note: I saw someone else had encountered this problem and I replied to it and boosted it. But it looks like it was posted in 2017? Hence this new post.

Hi all, reposting this from here: https://unix.stackexchange.com/questions/789849/xattr-c-not-removing-com-apple-finderinfo-attribute I came to this problem because my Xcode project was failing to build due to the error "resource fork, Finder information, or similar detritus not allowed" (was trying the solutions on this post). Basically, running xattr -cr . in the terminal on my project directory removes all extended attributes except com.apple.FinderInfo, which stays on all .xcodeproj and .xcworkspace files. I've tried everything under the sun, from sudo to xattr -d to dot_clean to tar to rsync and nothing works. Is this just an immortal attribute that can never be removed? I'm truly at a loss here, this is for my senior thesis project.

Every time my app runs in the simulator I see this error: Warning: Error creating LLDB target at path '/Users/aaronsmith/Library/Developer/Xcode/DerivedData/Babylist-ahvzjxxrpawwqhecszqeyvjstfca/Build/Products/Debug-iphonesimulator/Babylist.app'- using an empty LLDB target which can cause slow memory reads from remote devices: the specified architecture 'arm64--' is not compatible with 'x86_64-apple-ios13.2.0-simulator' in '/Users/aaronsmith/Library/Developer/Xcode/DerivedData/Babylist-ahvzjxxrpawwqhecszqeyvjstfca/Build/Products/Debug-iphonesimulator/Babylist.app/Babylist' What is this? I'm on an M1, no build issues. It makes me think the simulator is running under rosetta with x68_64. But I didn't choose to do that. Mac OS Ventura. Xcode 14 RC.
