I’ve noticed a strange bug in Xcode 16 and Swift. When a preview is rendering and hasn’t finished yet and you run an app to debug, Xcode is launching two instances of the app. Has anyone else noticed this issue? If you let the preview finish rendering before running the app, this doesn’t happen. Very odd.

I have a major problem with team membership and Xcode. I work in a company, where my apple account was added to the development team with app manager role. I can see that on the apple portal, everything seems fine there. I have been also provided with the provisioning profile for the project and signing certificate of the company. However, when I log into Xcode the team does not show up anywhere. I am able to build the app, but cannot distribute to TestFlight (or anywhere else). When I use manual signing to choose the signing certificate it shows the "unknown team" message next to it. When I check my account in xcode it also only shows my personal team and does not allow to pick any other one (doesn't show any other one). When I click the "+" button on my xcode account to add a certificate an error pops up: "You already have active certificate or a pending request". I do have a pending request to enroll into apple developers program, but everyone says you don't need one if you are added to the team, you can just operate as a team member. Finally, when trying to upload to TestFlight, the following error is displayed: "No team for account ***" I have tried deleting and re-adding all the certificates. I have tried logging in and out of Xcode, I have tried deleting and re-adding my account in Xcode. I have tried reloading everything. My account was deleted and re-added to developers team. Nothing worked. I don't know the source of the issue, nor does my employer. I am new to ios development and this is my first project. Please help!

I am editing my iOS project in Xcode 16 and want to use the "Swift Compiler - Upcoming Features" section of the build settings to selectively enable the new Swift 6 language features. I have read the instructions for doing this and have dowloaded an Apple sample project and can see that section under the project and target-level Build Settings in the sample project However, when I open my Xcode project in XCode 16 that section does not appear. Is there any way for me to influence how Xcode 16 displays the build settings? In fact, no "Swift Compiler" sections appear at all under my project Build Settings (All | Combined). There is a "User-Defined" section that has the Swift Version, Compilation Mode and Optimization level. The project itself is several years old and was on a very old project version. I have upgraded my project document format to "Xcode 16" but it made no difference. I have compared my project and the sample project in a text editor and both seem to have similar structure. I tried removing unused and outdated settings from my project but that also had no effect. Is there an alternative to deleting my project file and adding the source files to it? I have a large project with multiple targets so that would be something I'd rather not do.

I updated Xcode and MacOS recently and haven't been able to compile my Flutter app on iOS devices/simulators since then. The error keeps changing every time I run it but here's one of the output in the terminal after running flutter run: Uncategorized (Xcode): Command SwiftGeneratePch emitted errors but did not return a nonzero exit code to indicate failure Error (Xcode): no such file or directory: '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/Session.modulevalidation' Error (Xcode): stat cache file '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/SDKStatCaches.noindex/iphonesimulator18.0-22A3362- db63dc9361471f152f572502bdbfe70a.sdkstatcache' not found Error (Xcode): unable to rename temporary '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/3F9VRK3CXAUUD/UIKit-1KHQ7M05IF VXC-56601391.pcm.tmp' to output file '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/3F9VRK3CXAUUD/UIKit-1KHQ7M05IF VXC.pcm': 'No such file or directory' Error (Xcode): could not build module 'UIKit' /Users/chiragbhansali/Chirag/Coding/Projects/app/test/build/ios/Debug-iphonesimulator/Flutter.framewo rk/Headers/FlutterAppDelegate.h:7:8 Error (Xcode): could not build module 'Flutter' /Users/chiragbhansali/Chirag/Coding/Projects/app/test/ios/Runner/GeneratedPluginRegistrant.h:9:8 Error (Xcode): failed to emit precompiled header '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/Runner-eifcguceazlwumgsyzegclqdrbqt/Build/Intermed iates.noindex/PrecompiledHeaders/Runner-Bridging-Header-swift_PB6A5GFLTNPC-clang_3F9VRK3CXAUUD.pch' for bridging header '/Users/chiragbhansali/Chirag/Coding/Projects/app/test/ios/Runner/Runner-Bridging-Header.h' Uncategorized (Xcode): Command PrecompileSwiftBridgingHeader emitted errors but did not return a nonzero exit code to indicate failure Uncategorized (Xcode): Command SwiftEmitModule failed with a nonzero exit code Uncategorized (Xcode): Command SwiftCompile failed with a nonzero exit code Could not build the application for the simulator.

I add the following info in the build settings of my app. Then I also add the icon to my asset. I build the app, it works normally, but I notice that when I changed the icon to 'AppIcon-Defaults', The icon change alert didn't appear. but it succeeds . I uploaded the archive to App Store I got: ITMS-90895: Missing Icon - The Info.plist key CFBundleIcons.CFBundleAlternateIcons contains an entry “AppIcon-Defaults” that references asset “AppIcon-Defaults.” No such asset is present in the asset catalog. Then I use xcrun --sdk iphoneos assetutil --info Assets.car to check the assets inside the archieved app, It have the asset.

We've encountered a critical issue with the new linker of CLT16 (version 16.1.0.0.1.1729049160) that prevents proper initialization of BLOCK DATA. BLOCK DATA are used to initialize global variables in our Fortran code, and its failure to initialize those variables leads to a program crash. This affects our community of more that thousand scientists worldwide. The current workaround is using the -ld_classic linker option. However, this option is deprecated and will be removed in a future release, as described in the Xcode release note. I've attached a minimal example that reproduces the problem using GNU gfortran with the following instructions (the attached main.f.txt and bd.f.txt need to be rename to main.f and bd.f, respectively): gfortran -c bd.f gfortran -c main.f ar rv libtest.a bd.o main.o gfortran -ld_classic -o good.x -L. libtest.a gfortran -o bad.x -L. libtest.a Running the two programs, one can see that the BLOCK DATA are not initialised without the option ld_classic, $ > ./good.x 3.7273802569289098 2.8083922366048202 $ > ./bad.x 0.0000000000000000 0.0000000000000000 We kindly request your attention to this matter and a prompt solution or alternative workaround. Best regards main.f.txt bd.f.txt part.txt

Anyone else notice that Xcode 16.1 seems to have stopped building universal binaries for both debug and release builds even though under "Build Settings-Build Active Architecture" both Debug and Release are set to NO. We had been using the universal binary builds out of Debug for preliminary tests on Intel based machines. The Architectures setting is set to: Standard Architectures (Apple Silicon, Intel) - $(ARCHS_STANDARD). I started a brand new empty app and it does the same thing. A workaround is to set the Destination in Xcode's menu bar to "Build on Any Mac" and then find the binary and drag it to the Intel computer. You can't run that one though from Xcode. Another workaround is to build an Archive and drag that one.

When renaming A.value, it also causes the value inside the conditional compilation in checkRename to be renamed. How to resolve or avoid this situation? class A { let value = "1" } class B { var value = 0 } func checkRename() { var b = B() #if os(iOS) b.value = 456 #elseif os(macOS) b.value = 789 #endif } Xcode Version 15.4 (15F31d).

I'm running a macOS 15.2 guest on a macOS 15.1.1 host with UTM. I'm trying to install Xcode from within the App Store but cannot login to the App Store. When I enter credentials and click 'Sign In' I get the Error 'An unknown error occurred'.

Hi, I'm setting up Xcode and after updating MacOS to 15.2 and Xcode to 16.2, I cannot download the Predictive Code Completion Model. I've done some research and I haven't found any solution, specially since most people suggest that it randomly fixed itself, which for me hasn't been the case. I've tried restarting my Mac, uninstalling and reinstalling Xcode multiple times, I've also reinstalled MacOS from Recovery and haven't found any success (I'm also not running Xcode inside a VM, as I've seen this can cause some problems in this case). This is the error that I receive when I attempt to download the model: And here are the details: The operation couldn’t be completed.

My app controls the cursor within its text area. Upon touching the screen the ios moves the cursor when dragging. The app cursor and the IOS cursor are now out of sync. Is there a way to set the app cursor to the IOS cursor? I have checked many sources to no avail. Thanks for your help. Charlie

I'm getting hundreds of the message below in Xcode. I've narrowed it down to when I instantiate the following AVAudioUnitComponentManager.shared() Message send exceeds rate-limit threshold and will be dropped. { reporterID=231700600717315, rateLimit=32hz }

Whenever I run anything in xcode it opens an extra terminal that runs the program then exits immediately, but the app still runs through the normal xcode launch. It's not a huge issue but It's getting really annoying to realize I have like 7 windows of terminal open that are just doing nothing. Has anyone had this issue before?
