Apple Watch SE2 Xcode Debugging Issues
I currently own an Apple Watch SE2 device. However, when I try to debug from the watch to the actual device, the connection loss issue occurs all too often. Once the connection is lost, it continues to try to connect in the Disconnected list on the Xcode "Devices and Simulators" screen and is in a loading state. Very often, even when the connection is established and you are trying to start debugging, it drops out. Xcode cannot debug properly on the actual device. I later found out that the Apple Watch SE2 does not support 5.0 Hz Wi-Fi, only 2.5 Hz. I think that might be the cause. Is this phenomenon less likely to occur if you debug on an actual device such as a regular Apple Watch 7/8/9 or Ultra model? In fact, if debugging is difficult with the Apple Watch SE model, I am wondering whether I should purchase an additional Apple Watch. Or is there another way to improve this issue? It would be nice if the Apple Watch could be debugged by connecting it to a Mac with an actual cable like the iPhone. I am wondering if there is a way to disable and enable network debugging in Xcode. In the past, debugging the watch using only Bluetooth with the iPhone in Xcode seemed to be more stable. Except for the Watch, the iPad doesn't have any major issues with Wi-Fi debugging on the iPhone.

macOS Sequoia: Shared UserDefaults don't work (the app-group is set as per macOS 15 Sequoia requirements)
I use shared UserDefaults in my Swift FileProvider extension app suite. I share data between the containing app and the extension via User Defaults initialized with init(suiteName:). Everything was working fine before macOS 15 (Sequoia). I know that Sequoia changed the way the app group should be configured. My app group is know set to "$(TeamIdentifierPrefix)com.my-company.my-app". But the containing (UI) app and the Extension read and write from and to different plist locations although the same app-group is specified for both targets in XCode. The containing app reads and writes to "~/Library/Preferences/$(TeamIdentifierPrefix)com.my-company.my-app.plist" The Extension reads and writes to "~/Library/Containers/com.my-company.my-app.provider/Data/Library/Preferences$(TeamIdentifierPrefix)com.my-company.my-app.plist" Both of these locations seem completely illogical for shared UserDefaults. I checked the value returned by FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "$(TeamIdentifierPrefix)com.my-company.my-app" in both the containing app and the Extension and the value in both of them is the same but has nothing to do with the actual paths where the data is stored as provided above. (The value is as expected - "~/Library/Group Containers/$(TeamIdentifierPrefix)com.my-company.my-app/" P.S. Of course, $(TeamIdentifierPrefix), my-company and my-app here are placeholders for my actual values.

Getting "Invalid binary" when trying to submit app to review
I'm trying a release a new version to one of my Apps. Last success was January 25, but now I'm keep getting "Invalid binary" error no matter what I'm doing, with no further info about the source of the problem. I clarified all settings are correct and tried different ways (direct upload from xCode, using Transporter). I even rollback my project to the same version I used when I was able to release a new version (Jan 25), and with the same project content - same code, same settings, only changed version - I also got the same error response. Any idea?

How to create a second target for an app with a linked App Clip?
I have a SwiftuI App which includes an App Clip. There is one target for the iOS app and one for the App Clip. All good. But I want to create a new target for the test flight app so that test users can distinguish it from the App Store app. E.g. Test Flight app has a different icon asset file in the target but is identical in all other aspects. However, when I try to build the test flight target I see the message: The com.apple.developer.parent-application-identifiers entitlement (...]') of an App Clip must match the application-identifier entitlement ('...') of its containing parent app. This implies that I’d have to change the entitlement of the app clip, which would mess up the production version so I clearly don’t want to go that route. Any ideas how to overcome this conflict?

ZSH Won't Run an M1 Command Line Tool Built in Xcode
I have a command line tool that zsh refuses to run when built for Apple Silicon or as a univerisal binary (the specific message is zsh: killed TOOL_NAME). I can only get it to run if I build it exclusively for Intel/Rosetta. Running/debugging from within Xcode works fine for any architecture. The tool is a very simple C/C++ unix command-line tool; it doesn't have any external dependencies beyond the C runtime and the C++ STL. I suspect something in code signing is going awry, but I've tried various team and certificate combinations without any luck. I've also tried enabling/disabling the app sandbox, also without any luck. (The app is not for distribution so it doesn't really need to be code signed at all.) Any suggestions?

App Closes After Apple Sign-In on Vision Pro When Launched Directly
I am experiencing an issue with Apple Sign-In on Vision Pro. When I build and run the app from Xcode, everything works fine—after signing in, the app returns to the foreground as expected. However, when I launch the app directly on Vision Pro (not from Xcode), after completing the sign-in process, the app does not reopen from the background automatically. Instead, it closes, and I have to manually tap the app icon to reopen it. Has anyone else encountered this issue? Is there a way to ensure the app properly resumes after sign-in without requiring manual intervention?

Xcode does not see Apple Vision Pro headset
I have had my Apple Vision Pro headset working with Xcode before, but it has been a while since testing in the headset. Today, Xcode on my M1 Mac Studio could not see my Apple Vision Pro to run code on the headset. I have updated my headset to visionOS 2.4 developer beta Both Mac and headset are on the same Wi-Fi network (I am typing this on my Mac via Mac Virtual Display). Headset has developer mode turned on. Initially I tried on the latest macOS (15.3.x) an Xcode (16.2) releases, but Xcode failed to find the headset. I installed the lated Xcode beta (16.3 beta), but it still failed to find the headset. I installed the latest developer beta on my Mac (15.4), but neither Xcode (16.2) nor Xcode beta (16.3) can find the headset. When I try to manage devices in Xcode, my Apple Vision Pro headset does not appear. Any idea what I am missing?

Problem recording CPU Counters on an M1: xctrace record: Failed to start the recording: Failed to force all hardware CPU counters
Context I'm trying to profile a binary (a simple C++ program compiled into dummy.o) and collect CPU Counters data. I have a configuration that works fine from the Instruments Counters GUI (see Screenshots below). I've exported this configuration to a template file named prof1.tracetemplate. Problem When I try to run a recording with that same template from the command line with xctrace (I also tried with sudo): $ xctrace record --template prof1.tracetemplate --launch dummy.o I get the following errors: Starting recording with the prof1 template. Launching process: dummy.o. Ctrl-C to stop the recording Run issues were detected (trace is still ready to be viewed): [Error] Unexpected failure: Couriers have returned unexpectedly. [Error] Failed to start the recording: Failed to force all hardware CPU counters: 13. [Error] Failed to pause recording session: Cannot pause session session unless it's running.

No new Xcode beta Since 16.2 Release on Dec 11
Not a question, but a surprise. Did I miss something, but apparently there has been no new beta release (16.3) since Release of 16.2 on Dec 11. 2 months without betas is really unusual (in fact, it never happened and usually, next beta n+1 is even released before the final release of version n). So does that mean 16.3 will be a major update ? Wait and see.

How to package a static library and headers into an XCFramework?
I have static libraries and headers of a C++ project that I believe are correctly built for iOS and iOS Simulator destinations. The C++ project is built via CMake with something like: cmake dirName \ -G "Unix Makefiles" \ -B buildDir \ -DCMAKE_INSTALL_PREFIX=installDir \ -DCMAKE_SYSTEM_NAME=iOS \ -DCMAKE_SYSTEM_PROCESSOR=arm64 \ -DCMAKE_OSX_ARCHITECTURES=arm64 \ -DCMAKE_OSX_SYSROOT=$(xcrun --sdk iphonesimulator --show-sdk-path) \ -DCMAKE_OSX_DEPLOYMENT_TARGET=15.0 ... cmake --build buildDir --config Release --target install I believe those are all the important parameters. This gives me a static library (.a) and headers that I believe should be compatible with arm64 iOS simulators, and I do this same thing for x86_64 architecture with simulators and for actual iOS non-simulator via the iphoneos SDK path. I'm pretty sure this gives me the correct static lib and headers. Let's assume it does because I'm not able actually create the XCFramework to know if they're right. This does work with a macOS lib and headers, but I need iOS for this library. How do I package this into an XCFramework now? This Apple developer articles says I should be a able to create an xcframework via xcodebuild -create-xcframework -library libName.a -headers include but when I try to do this with my my iOS arm64 simulator static lib I get: error: binaries with multiple platforms are not supported '/Users/.../install/ios-arm64-simulator/libName.a But, when I run: lips -info libName.a I get Non-fat file libName.a is architecture arm64, so, I'm not sure what to do here. Trying to extract arm64 from that static library also produces an error as it it is just an arm64 lib. I'm not really sure what's going on, but from reading online this specific command, xcodebuild -create-xcframework is a consistent pain point in the process of trying to get an XCFramework, and the seemingly only workaround is to archive a framework project and then create the xcframework via xcodebuild -create-xcframework -archive MyFramework.xcarchive -framework[or -library]. However, how am I supposed to get this static lib and headers into a suitable xcodeproj so that I can archive it correctly? Everytime I try to copy the headers and static lib into the Framework xcodeproj and set what I believe are all the correct settings, my .xcarchive is always empty. Does anyone have any advice here on how to get this to work? The main impetus for trying to get this C++ static lib and headers into an XCFramework as that seems like the only valid way to link a 3rd party C++ lib to an SPM package and have the C++ package be interfaceable with Swift.

Broken Xcode 16 autocomplete using Tab
I've recently upgraded to Xcode 16 and noticed a change in how the Tab key functions during autocomplete. (not-replied-but-closed post: https://discussions.apple.com/thread/255762888) Previously, pressing Tab would extend the typed text up to the first point of choice. For example, we have two classes: NSViewController and NSViewCoordinator BEFORE, typing: "NSV" + Tab used to complete to NSViewCo Now, in Xcode 16, pressing Tab selects the first suggestion by default, instead of completing up to the choice point. That is very inconvenient because very often I want just see all possible cases with some prefix...without need of typing all prefix manually. Seems there is no way to restore the previous behavior and that looks very very sad. I have reverse engineered Xcode 16...and what I get? They just install new CodeCompletion handler instead of old one without any chance to configure this behaviour by settings or UserDefaults =\ Hope this thread would raise votes and attract Xcode devs here

Where is swift assist?
Swift assist has been announced by apple this year. I have waited Xcode 16.2 release before posting this because I was still hopping for swift assist this year but apple DIDN'T release swift assist and they haven't post anything about swift assist reported or something... What's going to happen with swift assist? Coming next year?

"could not build module" errors on Xcode 16.2
Hello all:) I am using Xcode 16.2, react native 0.76, simulator -> iPhone 15(17.0), mac M1 Sequoia 15.2. Many "could not build module" errors appear while building files inside iPhoneSimulator18.2.sdk. The think is that I don't even use this simulator and if I try to delete it the Xcode hides all other simulator options and requires 18.2 to download.. Of course I already tried to clean and delete and reinstall everything but nothing works.. Any help is welcome:) Thanks!
