I'm trying to improve my build time on macOS by not building for x86_64. I've got the following settings: This gets Xcode not to build x86_64 for my app, but not all the package dependencies. I've updated most of the packages to swift-tools-version: 6.0 but FlatBuffers is still on 5.8 and .macOS(.v10_14). GPT claims: If your deployment target is set to macOS 10.15 or earlier, Xcode may force x86_64 support for compatibility reasons. But Xcode is building x86_64 for ALL my packages, even the ones that don't depend on FlatBuffers. When I open a package in Xcode that depends on FlatBuffers, then it builds arm only, so that may be a red herring. Not sure what else to try.

Working with .xctestplan files reminds me very much of working with project files and nibs and storyboards back in the day 😅 It seems that they are non-deterministic. This means that every time we add a new test module or edit the inclusion rules at all the whole file is recomputed. But it doesn't have a fixed order so everything in the file changes. It makes it very difficult to see what has happened in PR reviews and causes conflicts any time anything is changed. TBH... because it isn't alphabetical, even just finding a particular test suite is difficult without changes. Are there any plans to bring this file format up to date with the likes of xcodeproj and xib files? It would help massively while working with source control in a larger team. Thanks

Hi, Our team is facing an issue where the os log message is not fully printed in the Xcode console. Even when using Debug → Attach to Process by PID or Name, the logs appear truncated (Both simulator and physical device). We noticed that the Xcode 15.0 release notes we saw that there is some truncation made for debug lines in console. We also tried checking the logs using Console.app, but the truncation remains. If limitation is there how much maximum lines it can print ? Could anyone please provide guidance on how we can view the complete logs? Any suggestions or workarounds would be highly appreciated.

Hi, is there documentation on how to write a deep link that will open Xcode on a given file, and optionally a line number? I know about xed, and I would like exactly that functionality, but in link form, so that I can link to a certain file from an app such as Obsidian or from a README.md file. I checked Xcode's Info.plist and it understands several URL schemes, the most promising of which is xcode://, which successfully launches the app, but no matter what I tried, I get an error dialog telling me that Xcode did not understand the URL. Any help on this topic would be greatly appreciated. Victor

I've got a very simple command-line Swift project that contains a couple of OpenGL shader source files. They need to be accessed at run-time in order to be compiled and linked. For initial debugging, I hard-coded the absolute path to their location in the Xcode project directory, but I switch back and forth between two machines (MacBook Pro and Mac Studio) for which the project paths are different, so this doesn't work well. To solve this, I thought I could get Xcode to copy the shader sources over with the executable file at build time. I'm aware that technically, command-line apps have no resource bundle, but the "Build Phases" -> "Copy Files" section of the project configuration isn't disabled for my project, so I assumed that it could handle this. I added the two shader source files to the set of files to copy, via the "+" button, and set the Destination to "Products Directory". I left the "Subpath" field blank. AFAICT, nothing happens: the "Products/Debug" sub-directory of "~/Library/Developer/Xcode/DerivedData/..." has the executable, but neither of the shader sources. In fact, they don't appear anywhere inside ~/Library/Developer/Xcode. Okay, perhaps I need to uncheck "Copy only when installing" in the project config? Sadly, as soon as I click to uncheck it, Xcode crashes, even if that's the very first thing I do immediately after Xcode restarts. FWIW, I'm running Xcode 16.2 on a late 2019 MacBook Pro running Sonoma 14.6.1, but I'm pretty sure I've experienced the problem on my 2024 Mac Studio as well.

Xcode 16.2 (and also Apple Configurator) randomly stopped working since today morning. Upon opening, the application crashes -> "unexpectedly quit". I've tried restarting the Mac, I reinstalled Xcode, still the same issue. This issue is currently on my MacBook Pro M4 on macOS Sequoia 15.3.1.

I have a Mac Mini (M4) running macOS Sequoia 15.3.1. I very recently downloaded and installed the current version of XCode from the app store. I have not added any extensions - it's a vanilla, un-customized, un-enhanced installation. I have two user profiles (accounts) on my Mac: one Administrator and one Standard, each using a different apple account. I am using the Standard user account to learn XCode. When I attempt to set up a project, I get an error message when Xcode initially tries to save the (provided) project template file. The error states: "Failed to save Project2.xcodeproj. The backing file has been modified outside of XCode." I am using a NAS drive to store my project file. I have also tried saving it to the Desktop. It makes no difference to the error wherever the file is being saved. Similarly, I tried changing the Standard user account to an Administrator account to see if it was a privileges problem. Again, it made no difference to the error message. (So I changed the account back to a Standard user). I have tried googling the error but I only find references to problems related to extension/add-in products to XCode: none of which have I added to my XCode installation. I am attaching screenshots of the steps through the project creation process. Hopefully someone can tell me what I am doing wrong or what the problem is. Thank you.

Hello! I'm experiencing a persistent SwiftCompile warning that I haven't been able to resolve for several months: <unknown>:0: warning: default will never be executed Observations: Appears randomly across different files during the build. No source location or line highlighting is provided. Persists across clean builds and project reopenings. Occurs in both Xcode Cloud and local builds. What I’ve tried: Ensuring all switch statements on enums explicitly handle every case. Removing default cases from fully covered enum switches. Refactoring optional enum handling (e.g., using if let instead of switch). None of these resolved the issue. Any guidance would be greatly appreciated! Project details: Xcode: 16.2 Swift: 6 iOS Target: 17.0+ UI: SwiftUI-only (no UIKit) Dependencies: SwiftPM

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! 😀✌️

When I try to build my project in Xcode (from Unity AR) project, it throws me these errors: I feel like I've tried everything to make the LaunchScreen work. I downloaded xcode the night I tried running this build, so the whole deleting and redownloading and restarting everything didn't work. I've tried making sure my macbook and terminal are fully up to date. I literally can't find a solution! Please help!! I will also say, I'm fairly new to App building, Xcode, and Unity. But this does seem like a barrier that is stopping me from testing my project.

I just started working with Flutter. I use a Macbook m2 and my phone is an iPhone XR. I made a very simple application but no matter what I did, I couldn't start my application on my iPhone XR. I got help from all the AIs but we couldn't do it. I deleted everything including Xcode, Android Studio and Flutter and reinstalled them and I followed the SDK installation step by step on the Flutter page but I can't run my project on Xcode. I entered my Apple account including all the signings and certificates via the .workspace file extension but it didn't work. The error I get from Xcode keeps changing. We installed podfiles with the support I got from the AIs and after some fiddling, I got the only error right now: Command PhaseScriptExecution failed with a nonzero exit code

Hi, I currently have an app that connect to an arduno via CoreBluetooth. However, the app no longer discovers the arduino when the operating system was upgraded to iOS 18.3.1, however on iOS version 17.6.1 the ardiuno was discoverable I was able to test this theory on two different phones each with different iOS versions. Why are my peripherals no longer being discovered with this update? and what is the solution?

I'm using a CMake project and Xcode decided that it would ignore or completely change my file tree to some random one. It has Source files (not a folder in my project) and completely ignores my class folder and header folder. It created it's own Header Files folder. How do I revert this? Why is this even a thing.

I am currently working on creating a virtual interior design app. Can an app made with the Room Plan API be used on iPhones without LIDAR? If so, how much accuracy would be lost compared to iPhones with LIDAR?

Hello, I'm trying to use Xcode's ARKit Session replay functionality. I have a capture I made using Reality Composer and when trying to use it with Xcode's replay functionality the installation and debugging process seems stalled forever. I've gotten it to work once so I know the capture file is functional but I have never gotten it to work a second time, even though I didn't change any settings. No amount of restarting Xcode, the Mac, or the iPhone seem to work. I have also tried cleaning build folders, reinstalling the app, and clearing DerivedData. I can confirm from the Xcode logs that the app installs correctly but the app never launches. If I unselect the checkbox for "ARKit Replay Data", the app launches and debugs nearly instantly. I have tried letting it "attach" for up to 10 minutes to no avail.
