App Not Appearing in "Available Apps" List in Watch App
I’ve developed an Apple Watch extension for an existing iOS app. When I run the app on the watch via Xcode using the simulator, everything works fine. However, when I try to install it on my iPhone, the Watch app doesn’t show it in the "Available Apps" list, so I can't install it on the watch. The Apple Watch is connected to my iPhone, and I can see other apps available for installation without any issues. I also created a brand new project with watchOS support to troubleshoot, but the same problem occurred. Any ideas on how to resolve this?

Unable to launch + Attach to Mac Widget (Sonoma + Xcode 15)
Attempting to launch a widget in Debug mode on Sonoma from Xcode 15 is failing with the following message: attach failed (Not allowed to attach to process. Look in the console messages (Console.app), near the debugserver entries, when the attach failed. The subsystem that denied the attach permission will likely have logged an informative message about why it was denied.) Looking in console I see this message: macOSTaskPolicy: (com.apple.debugserver) may not get the task control port of (MacGalleryWidget) (pid: 1851): (MacGalleryWidget) is hardened, (MacGalleryWidget) doesn't have get-task-allow, (com.apple.debugserver) is a declared debugger(com.apple.debugserver) is not a declared read-only debugger What Xcode settings should I be looking at to rectify this? I suspect I may have something that's out of whack.

NO_CRASH_STACK with different number of crashes from the App Store.
Hello. For the last few months I have been facing a situation for which I do not understand either the reason or the solution. Here is an example for the last few weeks: In App Store Connect it shows 214 crashes for the last week In Xcode it shows 56 crashes for the last 2 weeks without stack traces (NO_CRASH_STACK) In Firebase Crashlytics there is not a single crash. When I click "Show in Finder" it opens a folder with .xccrashpoint files. As far as I understood from the instructions on posting crash reports - this is not what is needed. Interesting point: it looks like the errors occur on iOS 15-16 devices. I have several questions: Why is the number of crashes in Xcode different from the number in App Store Connect? Where are the other crashes? How can I understand what the problem is if there are no stack traces in Xcode?

error: type for self cannot be reconstructed: type for typename
Hi, i have met error below when i tried to po one attributes of an instance in my Xcode lldb: error: type for self cannot be reconstructed: type for typename "$xxxxx" was not found (cached) error: Couldn't realize Swift AST type of self. Hint: using `v` to directly inspect variables and fields may still work. Is there anybody met the same error before? I urgently want to know why this happen and how to fix this issue. My macOS Version is Sequoia v15.0.1, Xcode16.0. This problem showed after i upgraded my macOS and Xcode version.

CPListTemplate in CarPlay Simulator: Multiple Items Selected on Tap
I am encountering an issue while running my CarPlay app in the simulator using CPListTemplate. On app launch, when I tap on the first item in the list and then tap on the second item, both items remain selected instead of only the latest tapped item. This behavior does not align with the expected single-item selection functionality. Has anyone else faced this issue? Is there a workaround or a known resolution for this behavior?

CoreData in Swift Packages
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. When trying to load the model in the main app, I am getting CoreData: error:  Failed to load model named DataModel Code: In my swift Package: public class SamplePackageDataStack: NSObject {     public static let shared = SamplePackageDataStack()     private override init() {}     public lazy var persistentContainer: NSPersistentContainer = { let container = NSPersistentContainer(name: "DataModel") container.loadPersistentStores(completionHandler: { (storeDescription, error) in             if let error = error as NSError? {                 fatalError("Unresolved error \(error), \(error.userInfo)")             }         })         return container     }()     /// The managed object context associated with the main queue.

Xcode not omitting binary of static framework
I'm following the steps laid out in Creating a static framework which states: When a client links and embeds the framework, Xcode 15 or later omits the main binary from the embedded framework bundle because it’s already statically linked into the client. Specifically, I'm adding a new framework target to my project, and then changing the Mach-O type in its build settings to Static Library. What I'm observing when I build (debug or release) is that that the resulting framework folder inside of the app bundle still contains a binary. Furthermore, upon inspecting strings and symbols in both the main app executable and this library binary, it appears that my strings and symbols do end up in the main executable and not in the library binary. Does this mean that this binary is just a stub left behind? Is this intended? Can I safely delete this binary with a build phase script?

Xcode 16 Doesn't Display "Swift Compiler" Build Settings Sections
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.

how to inhibit -fprofile-instr-generate passed to linker
I'm struggling to build a driver for iPadOS in a particular project configuration. If I put the driver code and dext target into the same Xcode project which contains the iPad app, all is well. This is the way the Xcode driver template does it. However, I'd like to build and debug the dext on macOS, while eventually deploying on iPadOS. So I put the dext into a different project, which has a macOS target, a minimal iPadOS target and a DriverKit target. I made a workspace which contains both projects. I dragged the macOS project into the iPadOS project so that I can refer to the products of the macOS project (specifically, its driver target) as a dependency of the iPadOS target. Note that the main iPad app target depends on the driver target. So the workspace organization looks like this: Workspace iPad project main iPad app target (depends on driver) test project reference test project test macOS/iPad app target DriverKit dext target When I build the iPadOS target, it builds the dependent driver target in the macOS project, but it fails to link because Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/15.0.0/lib/darwin/libclang_rt.profile_driverkit.a is not found. If I just build the driver target directly in Xcode, there is no such complaint. I looked closely at the build logs, and I see for the failed link, there are these two linker flags set which are not set in the successful case -debug_variant -fprofile-instr-generate I can't seem to control the generation of this flag. I tried turning off the Profile switch in the Scheme editor for the driver, but is makes no difference. When I directly build the driver target, no -fprofile-instr-generate is set and it compiles and links. When i build the driver as a dependency of another target, -fprofile-instr-generate is passed to the linker, which fails. The obvious workaround is to put the driver source code into a separate driver target in the iPadOS project, but I'd rather have just one DriverKit driver for both platforms, with a few settings (such as bundle ID) controlled by a configuration file. Has anyone else encountered this problem, and know of a workaround?

Application crashes referencing callAsyncJavaScript
When referencing WebKit’s function callAsyncJavaScript, any iOS app crashes immediately on startup when running in simulator. On device, it does not crash. The error message is: dyld[9892]: Symbol not found: _$sSo9WKWebViewC6WebKitE19callAsyncJavaScript_9arguments2inAF17completionHandlerySS_SDySSypGSo11WKFrameInfoCSgSo14WKContentWorldCys6ResultOyyps5Error_pGcSgtF Furthermore, this only happens for some simulators. With Xcode 16.3, it’s simulators 18.0 and prior. With Xcode 16.4 RC1 it includes simulators iOS 18.5 and 18.4 but works correctly on earlier versions of simulator. The reproduction path is easy. Example file attached. This used to work about 3 weeks or a month ago, which is perplexing. As a workaround I replaced the function with evaluateJavaScript which does not crash, but that is not the desired method to use for us. The attached file can reproduce it easily - just refernece this view from the default ContentView in a new project. TestWebView.swift

Xcode 16.3 / 16.4 UINavigationBar rendering issue?
I've recently upgraded to Sequoia and Xcode 16.3 (now 16.4RC) and a significant change I've noticed vs 16.2 is that the height of UINavigationBar components in storyboards and XIBs is incorrect. Xcode 16.2: Xcode 16.4: This only affects simulated metrics in storyboard / XIB files. I have been unable to find any discussion of this issue anywhere online. Is this actually an Xcode bug that has gone unnoticed / unfixed or is there some underlying intentional change here that I'm unaware of?

Xcode 15 performance tests ignore baseline
I'm trying to write performance tests with Xcode 15, but it's not working: even though setting a baseline seems to work (baseline data files are created), Xcode seems to ignore that baseline altogether whenever the test is run. As a result, performance tests never fail, no matter how bad performance gets. The source editor persistently displays a “No baseline average for Time” message. Has anyone else encountered this? Figured out how to sidestep the issue? Of note, the issue is easily reproduced: create a new (macOS in my case) app project with tests, add a dummy performance test; run the test once and save its baseline, and despite this subsequent tests will always succeed, even if you significantly slow the dummy test down. (I've filed this as FB13330139)
