Hello, We're attempting to validate our application archive through Xcode but the application is crashing during the validate step and we're not sure why. Platform: macOS 15.1 Arch: arm64 We've confirmed that our developer agreements are up to date (a suggestion made by other posts on these forums). Other suggestions have been to downgrade Xcode but we're hoping there's another explanation. The application is quite complex - many libraries and framework - but executes as expected during development and testing. Crash Report Any insight into this error would be appreciated. We're sure it's something wrong with our plist or archive structure but the crash is limiting our ability to debug.

Starting Xcode 14, iOS Simulator is able to communicate with APNs in order to register for notification in the sandbox environment. I created a sample test for this. A dumb iOS application that registers for notifications. It has UITests to automatize the tap on the consent popup (it is not possible to ask for the permission via CLI sadly). Once the application registers, the AppDelegate method didRegisterForRemoteNotificationsWithDeviceToken is called and the device token is sent to a local server application (node.js). The test itself creates an iOS 18.6 Simulator with xcrun simctl, builds such app and run the tests through through CLI with xcodebuild. Running this on my personal Macbook Pro M1 2021 goes well every time, so I wanted to bring it on Github Actions (arm64 macOS machines), in order to test the works on a open source library I'm building (hapns). Contacting Github support led me to test this on a macOS image running inside a VM inside a Veertu Anka container on my personal Macbook Pro, due to an VM architectural limit suspicion. The results were the same: iOS simulator isn't able to receive the device token. Not even didFailToRegisterForRemoteNotificationsWithError is called (tested through some network probes-requests that communicate to the server which checkpoints the process reached). So, as asked, I've setup a repro-case to be run in the VM and I've collected VM diagnostics ready to be tested and attached. Does anyone know if there is some unspecified (or specified but buried in the documentation) limit for this? Thanks. Github discussion link for further details, repro-case and so on: https://github.com/actions/runner-images/issues/12747

It didn't happen with Xcode 16.2 that I used before, but after updating to 16.3, when I build the app, the following error is output to the console and the app doesn't run. dyld[2150]: Symbol not found: ___cxa_current_primary_exception Referenced from: <6B00A4F2-B208-3FDB-BA38-B7095AF0034A> /private/var/containers/Bundle/Application/B590DB18-9C66-4C9E-8330-104943419E60/Mubeat DEV.app/Mubeat DEV.debug.dylib Expected in: <7F51CB08-A0CA-386E-BB62-4B8BFB0CED9F> /usr/lib/libc++.1.dylib Symbol not found: ___cxa_current_primary_exception Referenced from: <6B00A4F2-B208-3FDB-BA38-B7095AF0034A> /private/var/containers/Bundle/Application/B590DB18-9C66-4C9E-8330-104943419E60/Mubeat DEV.app/Mubeat DEV.debug.dylib Expected in: <7F51CB08-A0CA-386E-BB62-4B8BFB0CED9F> /usr/lib/libc++.1.dylib dyld config: DYLD_LIBRARY_PATH=/usr/lib/system/introspection DYLD_INSERT_LIBRARIES=/usr/lib/libBacktraceRecording.dylib:/usr/lib/libMainThreadChecker.dylib:/usr/lib/libRPAC.dylib:/Developer/Library/PrivateFrameworks/DTDDISupport.framework/libViewDebuggerSupport.dylib After looking for another solution, I found a way to remove the -Objc option in Other Linker Flags, but this method only works on iOS 18.4 and doesn't work on other versions. Is there another solution?

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.

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! 😀✌️

I'm working on a macOS app that I want to give "Full Disk Access". When I run from Xcode, I get "permission denied" errors when reading a file in my home directory. What can I do so that I can run and debug from Xcode? I dragged the binary from the derived data folder to the System Preferences list for Full Disk Access, but that seems to do nothing.

With Xcode 14, the device selection on the bottom of the storyboard canvas has changed, and the iPhone 12 and 13 mini screens are no longer there, as well as there only being one model of iPad. Is there a way to add more devices to this section? I have simulators installed for these devices, and this is the way I've been checking compatibility so far, but this is not sustainable. I appreciate any help that you can give me.

I have a multi target project where every target relies on a built "web bundle" which is basically a collection of html, optimized images, and optimized javascript. Right now that web bundle is built in a pre build step by running a script. The script takes awhile to run and outputs to a folder that is referenced into the project via a PBXFileReference which is then referenced in the Copy Bundle Resources step. 96516AC22BF928DD00576562 /* build */ = {isa = PBXFileReference; lastKnownFileType = folder; name = build; path = "../web-ui/build"; sourceTree = "<group>"; } .... 96516AC32BF928DD00576562 /* build in Resources */ = {isa = PBXBuildFile; fileRef = 96516AC22BF928DD00576562 /* build */; }; As a step, I wrote an aggregate target that can also run this script. I specified its input and output files and turned off sandboxing. It does exactly what I need it to. Critically it is ran based on dependency analysis. If I modify any file in web-ui it rebuilds, if I dont I can repeatedly build the aggregate target and it will not re-run the script. This is perfect. A97590172E419CBA00741928 /* Build Web Bundle */ = { isa = PBXShellScriptBuildPhase; buildActionMask = 12; files = ( ); inputFileListPaths = ( ); inputPaths = ( "$(SRCROOT)/xcodescripts/build-web-bundle.bash", "$(SRCROOT)/web-ui/index.html", "$(SRCROOT)/web-ui/vite-env.d.ts", "$(SRCROOT)/web-ui/vite.config.ts", "$(SRCROOT)/web-ui/tsconfig.json", "$(SRCROOT)/web-ui/stats.html", "$(SRCROOT)/web-ui/postcss.config.js", "$(SRCROOT)/web-ui/package.json", "$(SRCROOT)/web-ui/justfile", "$(SRCROOT)/web-ui/src/", ); name = "Build Web Bundle"; outputFileListPaths = ( ); outputPaths = ( "$(SRCROOT)/web-ui/build/", ); runOnlyForDeploymentPostprocessing = 0; shellPath = /bin/sh; shellScript = "exec \"${SCRIPT_INPUT_FILE_0}\"\n"; }; You may notice I reference a src file. This is made possible via a flag USE_RECURSIVE_SCRIPT_INPUTS_IN_SCRIPT_PHASES which allows Xcode to check folder dependencies recursively. The problem is that my other targets do not automatically recognize that they need to run the "WebBundle" aggregate target in order to update a resource they copy in their "Copy bundle resources" phase. So I tried adding it as a Target Dependency. A9DE685B2E41C9A8005EF4E0 /* PBXTargetDependency */ = { isa = PBXTargetDependency; target = A97590132E419C1200741928 /* WebBundle */; targetProxy = A9DE685A2E41C9A8005EF4E0 /* PBXContainerItemProxy */; }; Unfortunately this breaks whatever magic was allowing the script to be run only when there are web bundle changes. Every build it runs the "Build Web Bundle" script. I think what I am missing is a way to specify in these other targets that a resource they are used to copying from the Xcode PBXFileReference is produced by the aggregate target. This way they can start to reason about the dependencies. Other possibilities are that I should be building the web bundle to a separate location. Or that these references are somehow broken in another way. To be clear the folder format is as thus project/ iOS/ client.xcodeproj web-ui/ build/ (web bundle build is output here and referenced relatively) src/ index.html (and other things)

Ok, I'm going crazy here. I have a static library for iOS that I want to build for the simulator. I use xcodebuild -destination="iOS Simulator" and then check the library using otool which tells me the platform is 6, which is Mac Catalyst. When I look at the output of xcodebuild, it says --- xcodebuild: WARNING: Using the first of multiple matching destinations: { platform:macOS, arch:arm64, variant:Mac Catalyst, id:00006041-0008492E3AA1801C, name:My Mac } ... It has the simulator listed too, way down the list: { platform:iOS Simulator, arch:x86_64, id:AB7A99B3-8D24-4F73-A42D-9BB45321928D, OS:18.6, name:iPad (A16) } When I put all of that into xcodebuild for the platform, it still says there are multiple matching destinations and chooses Mac Catalyst. Why? How? What? Does platform="iOS Simulator" mean nothing? How in the world does "Mac Catalyst" match "iOS Simulator"????? I don't want Mac Catalyst, I don't need Mac Catalyst, and I can't get rid of Mac Catalyst. Nothing I specify in xcodebuild results in anything I can build that will compile for the simulator. What the heck am I doing wrong?

Build succeed,but app startup failed.

Everytime when iOS simulator is launched I het a lot of repeated "*** quit unexpectedly" alerts. Where "***" is a mix of "managedappdistributiond","healthappd", and "findmylocated" Even after the simulator is launched I still het random "*** quit unexpectedly" alerts. Very annoying because the alerts deactivates the active window This is on an MacBook Pro M3 Max,, Xcode 15.2, Sonoma 14.2.1, it also happens with Xcode 15.1 A co developer (MacBook Pro M1 Max,Xcode 15.2, Sonoma 14.2.1) does not have the issue Any idea how I can prevent this from happening? Update Every mentioned service crash happens in libswiftCore.dylib at 0x1929f3938 assertionFailure(:_:file:line:flags:) + 248

Since iOS 18.2 the simulators have been missing the content under Apps menu for Settings. We are on to iOS 18.3 and still no Apps settings. @dts

Beginning April 24 releasing on the App Store requires using Xcode 16, iOS 18 SDK. https://developer.apple.com/news/upcoming-requirements/?id=02212025a Xcode only offers simulators for iOS 15. I had not been able to install and use previous versions. Does it imply iOS 15 is the minimum target allowed?

I have an iOS app with a QuickLook extension. I also added Apple Vision Pro in the target's General > Supported Destinations section. About one year ago, I was able to run the app on iPhone, iPad and Apple Vision Pro Simulators. Today I tried running it again on Apple Vision Pro with Xcode 26.0.1, but Xcode shows this error: Try again later. Appex bundle at ~/Library/Developer/CoreSimulator/Devices/F6B3CCA8-82FA-485F-A306-CF85FF589096/data/Library/Caches/com.apple.mobile.installd.staging/temp.PWLT59/extracted/problem.app/PlugIns/problemQuickLook.appex with id org.example.problem.problemQuickLook specifies a value (com.apple.quicklook.preview) for the NSExtensionPointIdentifier key in the NSExtension dictionary in its Info.plist that does not correspond to a known extension point. I tried again later a couple times, even after running Clean Build Folder Immediately, without any change. I can reproduce this with a fresh Xcode project to which I add a Quick Look Preview Extension and Apple Vision Pro as a supported destination. The error doesn't happen when running on Apple Vision Pro (Designed for iPad) or iPad Pro 13-inch (M4) destinations. What is the problem? I created FB20448815.

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 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?

From time to time while I'm editing code, Xcode 15.0.1 says "The file 'project.xcworkspace' has been modified by another application" asking me "Keep Xcode Version" or "Use Version on Disk". I didn't see this before 15.0.1 (or 14.1.1). Who changed the file? What should my answer be? Thanks.

The Files app in the iOS 18 beta simulator appears to be read-only. I am unable to: create folders copy files into it by dragging them from macOS safe files from safari I have been unsuccessful at finding a way to popular any file or folder in the Files app which is preventing me from testing some scenarios in my app where I import files using the files sheet. The earliest I tried was beta 3 and it still persists in beta 7. The iOS 17 simulator works fine in comparison. My mac is a 2019 macbook pro running Sonoma 14.5. To reproduce: New folder Launch Files app in iOS simulator Tap into "On my phone" From the top menu tap "New Folder" (nothing happens) Download a file Launch safari Find a file like a PDF to download Tap on the down arrow in the toolbar Files opens up with the filename in the textfield at the bottom The "Save" button is grayed out. Copy from macOS Open the Files app in iOS and browse to a local folder drag a file from the macbook onto the simulator the sheet appears with the filename in the text field The "Save" button is grayed out

Hi everyone, I’ve run into a strange issue while building my app with Xcode 26 beta 6 (targeting iOS 26). When I include an app icon created using Icon Composer, the build time jumps to over 5 minutes. During this time, I noticed that a utility called AssetCatalogSimulatorAgent is consuming a significant amount of CPU. If I remove the Icon Composer-generated icon from my target, the build completes in about 40 seconds. This behavior is consistent across multiple builds. Has anyone else experienced this? Is there a known workaround or optimization for icons created with Icon Composer? I’d love to keep using the new icon format, but the build time is becoming a real bottleneck. Thanks in advance!
