Under Xcode 26 beta 3 I'm trying to build a project which uses Metal. I've installed the Metal Toolchain 26.0 under Settings -> Components, but when I start a build it fails during the "Prepare build" step with the following error (repeated many times): stat(/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.1.5276.7.Pb9SLL/Metal.xctoolchain/usr/bin/clang): No such file or directory (2) I've confirmed that there is in fact no 'clang' binary in that directory. I've tried using xcode-select to set the Xcode 26 Beta app as the active developer directory, and xcodebuild -version shows: Xcode 26.0 Build version 17A5276g Any ideas on other things to try?

App Icon created with Icon Composer is empty for visionOS app We are developing a universal app, and the app’s icon was created using Icon Composer. Xcode 26, RC visionOS 26 and visionOS 2.5 App Icons on macOS, iOS, and iPadOS are correct We have archived the app for macOS and iOS and successfully uploaded it to the App Store. This strongly suggests that the App Icon configuration in our project settings is correct for these platforms. App Icon issue on visionOS However, the visionOS app icon is not working as expected: When testing on the Vision Pro simulator (versions 2.x and 26.0), the app icon appears empty. When archiving and submitting to the App Store, the process fails with the following error: The app’s Info.plist file is missing the CFBundleIcons.CFBundlePrimaryIcon key for the visionOS App Icon. This suggests that the project’s App Icon settings may not be correctly applied for visionOS builds. Request for assistance We are preparing to release our app, one of the first to support Liquid Glass, and would greatly appreciate guidance on how to resolve this issue with the visionOS app icon.

I just downloaded the latest Xcode 26 RC version, after the Apple Event. However, it prevents me from uploading the app to App Store Connect. I was able to upload and set up public TestFlight using the Xcode 26 beta version, and have been doing that for weeks. But the RC doesn't allow me to upload? I've also updated MacOS to 26 RC as well, not sure if that's an issue.

Hi, When submitting my iOS app that integrates the TwilioVoice SDK (v6.12.1+), validation fails with the following error: Upload failed with errors: Validation failed The app references non-public selectors in Payload/careqb.app/careqb: _isKeyDown, _modifiedInput, _modifierFlags (ID: 34774fb-ba69-4131-904f-694aead106d7) Steps to reproduce: Integrate TwilioVoice using CocoaPods (v6.12.1). Archive the app in Xcode 16.x. Validate for App Store Connect. Question: Is this a known false positive in App Store validation, or is TwilioVoice exposing private APIs internally? What’s the recommended way to proceed until Twilio releases a fix? Thanks, Ashutosh

Works fine to show achievements but not Leaderboards. Launching the Xcode Project directly on device, loading remote (not yet live) leaderboards without issue and submitting scores to them works fine as well. I was hoping that rather than going through the app store distribution leaderboards with all of their limitations I could instead run it locally and add scores to test the behaviour, but even though I can edit the achievements progress locally, I can't see any leaderboards being available... One out of 3 leaderboards started beginning of this september while the other 2 leaderboards won't launch until the game launch.

I am using GoogleMobileAds package dependencies and now when I want to archive and export an app I get this two warnings : Upload Symbols Failed The archive did not include a dSYM for the GoogleMobileAds.framework with the UUIDs [13B55A37-D103-36E1-8D7B-FA4EAB2C8146]. Ensure that the archive's dSYM folder includes a DWARF file for GoogleMobileAds.framework with the expected UUIDs. Upload Symbols Failed The archive did not include a dSYM for the UserMessagingPlatform.framework with the UUIDs [A3941120-02A1-30B5-8C28-BFC0F9496E16]. Ensure that the archive's dSYM folder includes a DWARF file for UserMessagingPlatform.framework with the expected UUIDs. I have updated the packages to 11.9.0 (lasted) and Xcode 16 to 16 RC (lasted also) and I would like to know how to fix this... With Xcode 15 I have no problem !! I can export with no warnings ! But now with Xcode 16 no... Thanks for helping !

Hello! I am trying to automate iOS builds for my Unreal Engine game using Unreal Automation Tool, but I cannot produce a functionnal build with it, while packaging from XCode works perfectly. I have tracked down the issue to a missing file. I'm using the Firebase SDK that requires a GoogleService-Info.plist file. I have copied this file at the root of my project, as the Firebase documentation suggests. I have not taken any manual action to specify that this file needs to be included in the packaged app. The Firebase code checks the existence of this file using NSString* Path = [[NSBundle mainBundle] pathForResource: @“GoogleService-Info” ofType: @“plist”]; return Path != nil; If I package my app from XCode using Product -> Archive, this test returns true and the SDK is properly initialized. If I package my app using Unreal Engine's RunUAT.sh BuildCookRun, this test returns false and the SDK fails to initialize (and actually crashes upon trying). I have tried several Unreal Engine tricks to include my file, like setting it as a RuntimeDependecies in my projects Build.cs file. Which enables Unreal Engine code to find it, but not this direct call to NSBundle. I would like to know either how to tell Unreal Engine to include files at the root of the app bundle, or what XCode does to automatically include this file and is there a way to script it? I can provide both versions .xcarchive if needed. Thanks!

After updating Xcode from 16.2 to 16.4, my xcodebuild commands began failing with "Server SSH Fingerprint Failed to Verify" when accessing Bitbucket repositories. During the build process, I could see Xcode's AuthenticationAgent running SSH with these arguments: /usr/bin/ssh -v -F /dev/null -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes -o SendEnv=GIT_PROTOCOL git@bitbucket.org git-upload-pack 'xxx.git' Xcode 16.4 appears to be ignoring my local ~/.ssh/known_hosts file and instead using its own managed known_hosts system (stored in IDESourceControlModernKnownSSHHostsDefaultsKey within com.apple.dt.Xcode.plist). My local known_hosts file contains three entries for Bitbucket: ssh-ed25519, ecdsa-sha2-nistp256, and ssh-rsa. After updating Xcode to 16.4 and opening my existing project, Xcode prompted with "Xcode can't verify the identity of a repository hosted on 'bitbucket.org'" and offered a "Trust" button. When I clicked "Trust," Xcode's managed known_hosts only stored the ecdsa-sha2-nistp256 entry for Bitbucket. I was able to resolve the issue by overwriting Xcode's managed known_hosts with the ssh-rsa Bitbucket entry from my local known_hosts file. Also, this behavior for some reason seems to vary between machines after the same Xcode update. So on my machine, Xcode 16.4 ignores the local ~/.ssh/known_hosts. My coworker's Xcode continues to use the local ~/.ssh/known_hosts file and works normally. What could cause Xcode 16.4 to handle SSH known_hosts differently on seemingly identical setups? Is there a hidden configuration that determines whether Xcode uses its managed known_hosts versus respecting the system's SSH configuration? Additionally, why did Xcode only store the ecdsa-sha2-nistp256 host key for Bitbucket when I clicked "Trust" instead of all available host key types, and why doesn't this single key type work?

Hello , am facing issue in submitting my app to store I have submitted my case to apple developer team my case ids "101969263018","101975805043". they told me to submit the report from feedback assistance my case id : FB12141270. but still I don't get any replay form feedback assistance. after that I submitted my case to DTS engineer case id : 2394373. got email to submit some file which I have submitted after that still I don't get any reply from DTS team. please help me to short out this issue. last one month am trying to short out this issue with apple developer team. still I don't get solution.

Hi There We are looking to download the iOS 18.4 Simulator Runtime but due to restrictions on internet access in our company we are unable to use XCode to download the required file. Is there an alternative location we can browse to and download the iOS 18.4 Simulator Runtime file? We checked the downloads sections of the Apple Developer site but can only find 18.2 version of the iOS Simulator Runtime. Thanks

I'm currently running Xcode 26 beta 7; it comes with macOS 26 beta 6 and can download iOS 26 beta 6. I can compile and test my app on simulators, but to upload the app to TestFlight I need a version of the Platform support more recent than beta 6. How can I download beta 9? In Settings -> Components I see only beta 6.

Hello all! Trying to find list of all XCode project parameters or build settings within description. Is there any documentation? Need something that will help me to understand list of project properties when running command in project folder: $ xcodebuild -showBuildSettings Command line invocation: /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -showBuildSettings User defaults from command line: IDEPackageSupportUseBuiltinSCM = YES Build settings for action build and target test: ACTION = build AD_HOC_CODE_SIGNING_ALLOWED = NO AGGREGATE_TRACKED_DOMAINS = YES ALLOW_BUILD_REQUEST_OVERRIDES = NO ALLOW_TARGET_PLATFORM_SPECIALIZATION = NO ALTERNATE_GROUP = staff ALTERNATE_MODE = u+w,go-w,a+rX ALTERNATE_OWNER = alexandr ALTERNATIVE_DISTRIBUTION_WEB = NO ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES = NO ALWAYS_SEARCH_USER_PATHS = NO ALWAYS_USE_SEPARATE_HEADERMAPS = NO and may other parameters Need to know meaning of this kind of parameters.

Hi, My app was recently rejected with the following message: The app references non-public symbols in App: _BIO_s_socket, _OPENSSL_cleanse The confusing part is that these symbols do not come from iOS system libraries. They are defined inside a third-party static library (gRPC/OpenSSL) that my app links. I am not calling any Apple private API, only linking against the third-party code where those symbols are defined. Questions: Why does App Review treat these symbols as “non-public” when they are provided by my own bundled third-party library, not by the system? What is Apple’s recommended approach in this situation — should I rebuild the third-party library with symbol renaming / hidden visibility, or is there another supported method? It would help to understand the official reasoning here, because it seems strange that a vendor-namespaced or self-built OpenSSL would cause a rejection even though I am not using Apple’s internal/private APIs. Thanks for any clarification.

If I use the new beta Icon Composer to make a .icon file for a macOS app, will it work for any macOS versions before 26? If not, can one build with both the .icon and the older asset collection icon?

I have a few issues. Support consultants responded to my review file by saying they wanted the image. 1- I logged in with the sandbox account I used for testing and took a screenshot of the Paywall screen. However, they said this screenshot wasn't accepted. The documentation explains how to log in to Testflight with a sandbox account and test it, but even though I tried testing on two different devices, I couldn't log in to Testflight or get the image they requested. 2- I closed my privacy policy and terms of use, and there's no problem. What else should I do? I'm stuck on the Testflight and sandbox sections. Can you help ?

I have been using tvOS 18 and Xcode 26 all summer without issue but since updating the tv to the latest tvOS 26 beta I am now unable to attach to debug builds. When using the Run button in Xcode the build completes, the tv screen goes black and then I see a warning in Xcode: Launching "App Name" is taking longer than expected. Do you want to continue to wait? LLDB is likely reading from device memory to resolve symbols. If I continue to wait after around 5 mins, in the Xcode console, I see: warning: libobjc.A.dylib is being read from process memory. This indicates that LLDB could not find the on-disk shared cache for this device. This will likely reduce debugging performance. But the process on the tv hangs indefinately. Hitting stop in Xcode disconnects the debugger but the app then finishes launching successfully on the TV. Trying to use "Debug > Attach to process > [App Name]" once it is running also just hangs the app and waits until stopped. When stopping the hung debugger I see an Xcode error with the following: Could not attach to pid : “1222” Domain: IDEDebugSessionErrorDomain Code: 3 Failure Reason: internal error User Info: { DVTErrorCreationDateKey = "2025-09-01 09:51:54 +0000"; DVTRadarComponentKey = 855031; IDERunOperationFailingWorker = DBGLLDBLauncher; RawUnderlyingErrorMessage = "Xcode has killed the LLDB RPC server to allow the debugger to detach from your process.

Hello, I’m having trouble enabling Background Location updates on my iOS app. Xcode: 26.0 beta Team: Individual Developer Program (paid, activated recently) Device: iPhone (physical device, registered and provisioned) Problem When building to device, I get the error: Provisioning profile "iOS Team Provisioning Profile: com.mybundle.id" doesn't include the com.apple.developer.background-modes entitlement. Automatic signing failed. On the simulator the build succeeds, but on device the signing fails unless I remove the background-modes entitlement from .entitlements. What I tried Enabled Background Modes → Location updates in Signing & Capabilities (UI only). Info.plist contains UIBackgroundModes = location and the required NSLocation…UsageDescription keys. Cleaned Derived Data, removed cached provisioning profiles (~/Library/Developer/Xcode/UserData/Provisioning Profiles). Changed Bundle Identifier to force regeneration of provisioning profiles. Deleted and recreated provisioning profiles from Xcode. Tried both with and without manual .entitlements edits. Current status Provisioning profile shows only App Groups, In-App Purchase, Push Notifications. Entitlements section in the downloaded profile is missing com.apple.developer.background-modes. As a result, background location cannot be enabled on device. Question Is this a known issue with Xcode 16/26 beta or with Individual Developer accounts? How can I get com.apple.developer.background-modes included in my provisioning profile so that location tracking continues while the screen is locked? Thank you.

I've created a "Transfer Learning BERT Embeddings" model with the default "Latin" language family and "Automatic" Language setting. This model performs exceptionally well against the test data set and functions as expected when I preview it in Create ML. However, when I add it to the Xcode project of the application to which I am deploying it, I am getting runtime errors that suggest it can't find the embedding resources: Failed to locate assets for 'mul_Latn' - '5C45D94E-BAB4-4927-94B6-8B5745C46289' embedding model Note, I am adding the model to the app project the same way that I added an earlier "Maximum Entropy" model. That model had no runtime issues. So it seems there is an issue getting hold of the embeddings at runtime. For now, "runtime" means in the Simulator. I intend to deploy my application to iOS devices once GM 26 is released (the app also uses AFM). I'm developing on Tahoe 26 beta, running on iOS 26 beta, using Xcode 26 beta. Is this a known/expected issue? Are the embeddings expected to be a resource in the model? Is there a workaround? I did try opening the model in Xcode and saving it as an mlpackage, then adding that to my app project, but that also didn't resolve the issue.
