My project build failed in Xcode Cloud(works well in my local Mac), and the error shows: Preparing build for App Store Connect failed The error message is not clear enough to help us find the solution to fix it. Can anyone help with it?

We are integrating Xcode Cloud into a larger CI/CD pipeline and ran into a serious limitation that makes proper build status reporting nearly impossible. Currently, Xcode Cloud provides only the following custom script phases: • ci_post_clone.sh • ci_pre_xcodebuild.sh • ci_post_xcodebuild.sh However, if a build fails during the actual Xcode build phase (for example, due to a compilation error, unit test failure, or signing issue), the ci_post_xcodebuild.sh script does not run. This means there is no guaranteed way to execute cleanup steps or send external notifications (e.g., updating build status in Bitbucket, Slack, or any external CI system). In any robust CI/CD setup, it’s critical to have a “finally” or “always run” hook that executes regardless of build success or failure — similar to post blocks in Jenkins, finally steps in GitHub Actions, or after_script in GitLab CI. Without such a mechanism, we cannot reliably integrate Xcode Cloud with the rest of our automation and monitoring ecosystem. This effectively breaks standard CI/CD practices, since external systems will never know if a build failed unless they constantly poll the Xcode Cloud API. Feature request: Please add a new hook (e.g., ci_finally.sh or ci_post_build.sh) that always executes after the build, whether it succeeded, failed, or was canceled. This would make Xcode Cloud much more suitable for professional CI/CD environments and allow proper integration with third-party systems.

So, our app imports CoreML and loads the CoreML models when starting up. Locally all tests succeed consistently. Running Tests on Xcode Cloud, they all fail with (UI and Unit Tests) App (6846) encountered an error (Early unexpected exit, operation never finished bootstrapping - no restart will be attempted. (Underlying Error: Test crashed with signal ill before establishing connection.)) the test instance is busy for 35min and then just aborts, with all tests failing. This sounds to me like the simulator is maybe showing some exception or is stuck? Or is it possible that xcode server runs in a special environment that gets stuck on loading CoreML models?

Hi there, We’re encountering this error in all of our builds when using the latest Xcode and macOS: The Metal Toolchain was not installed and could not compile the Metal source files. Download the Metal Toolchain from Xcode > Settings > Components and try again. In short, all builds are failing. I’ve tried fixing this by installing Metal and applying other solutions, but none of them worked reliably. Is there a way to ensure that the Metal Toolchain is installed on the CI machine?

In courses like Compose interactive 3D content in Reality Composer Pro Realitykit Engineers recommended working with Reality Composer Pro to create RealityKit packages to embed in our Realitykit Xcode projects. And, comparing the workflow to Unity/Unreal, I can see the reasoning since it is nice to prepare scenes/materials/assets visually. Now when we also want to run a Xcode Cloud CI/CD pipeline this seems to come into conflict: When adding a basic *.usdz to the RealityKitContent.rkassets folder, every build we run on Xcode cloud fails with: Compile Reality Asset RealityKitContent.rkassets ❌realitytool requires Metal for this operation and it is not available in this build environment I have also found this related forum post here but it was specifically about compiling a *.skybox.

Hi everyone, Starting today, my Xcode Cloud CI workflow can no longer successfully build iOS/macOS/visionOS targets. The Archive step does not report any errors, but the xcodebuild command hangs indefinitely and eventually fails with the following message: The step invocation hit a user timeout. The xcodebuild archive invocation timed out. No activity has been detected on stdout, stderr or the result bundle in 30 minutes. My iOS and macOS targets can still be built, but the build time has increased by 2-3x compared to before. That's interesting. After I removed the visionOS target, the iOS target also failed to build. Additionally, since today, I’ve noticed a significant increase in network-related errors in Xcode Cloud. There have been multiple failures to download dependencies from Homebrew or GitHub. I have confirmed that CI versions which previously built successfully are now failing, while running the same build commands locally works fine. Based on these observations, I suspect there may be an issue with the Xcode Cloud environment itself. Has anyone else encountered similar problems? Any suggestions or updates would be appreciated! Thanks!

Hi, We successfully migrated to the new AppIcon from Icon Composer. Everything works great on simulator and on real devices. We also released a manually generated build that works great. However when we build the same project from Xcode Cloud we get the following error: None of the input catalogs contained a matching stickers icon set, app icon set, or icon stack named "AppIcon" The previous line seems to indicate that no icon is passed: /Applications/Xcode.app/Contents/Developer/usr/bin/actool /Volumes/workspace/repository/Mail/Assets.xcassets --compile /Volumes/workspace/DerivedData/Build/Intermediates.noindex/ArchiveIntermediates/Infomaniak\ Mail/IntermediateBuildFilesPath/Mail.build/Release-iphoneos/Infomaniak\ Mail.build/assetcatalog_output/thinned --output-format human-readable-text --notices --warnings --export-dependency-info /Volumes/workspace/DerivedData/Build/Intermediates.noindex/ArchiveIntermediates/Infomaniak\ Mail/IntermediateBuildFilesPath/Mail.build/Release-iphoneos/Infomaniak\ Mail.build/assetcatalog_dependencies_thinned --output-partial-info-plist /Volumes/workspace/DerivedData/Build/Intermediates.noindex/ArchiveIntermediates/Infomaniak\ Mail/IntermediateBuildFilesPath/Mail.build/Release-iphoneos/Infomaniak\ Mail.build/assetcatalog_generated_info.plist_thinned --app-icon AppIcon --accent-color AccentColor --compress-pngs --enable-on-demand-resources YES --development-region en --target-device iphone --target-device ipad --minimum-deployment-target 15.0 --platform iphoneos However when I archive locally, the icon seems correctly referenced: /Applications/Xcode.app/Contents/Developer/usr/bin/actool /Users/<my name>/Developer/ios/infomaniak/apps/ios-kMail/Mail/Resources/AppIcon.icon /Users/<my name>/Developer/ios/infomaniak/apps/ios-kMail/Mail/Resources/Assets.xcassets --compile /Users/<my name>/Library/Developer/Xcode/DerivedData/Mail-fbgflwyftafvlmezepjlymckizhg/Build/Intermediates.noindex/ArchiveIntermediates/Infomaniak\ Mail/IntermediateBuildFilesPath/Mail.build/Release-iphoneos/Infomaniak\ Mail.build/assetcatalog_output/thinned --output-format human-readable-text --notices --warnings --export-dependency-info /Users/<my name>/Library/Developer/Xcode/DerivedData/Mail-fbgflwyftafvlmezepjlymckizhg/Build/Intermediates.noindex/ArchiveIntermediates/Infomaniak\ Mail/IntermediateBuildFilesPath/Mail.build/Release-iphoneos/Infomaniak\ Mail.build/assetcatalog_dependencies_thinned --output-partial-info-plist /Users/<my name>/Library/Developer/Xcode/DerivedData/Mail-fbgflwyftafvlmezepjlymckizhg/Build/Intermediates.noindex/ArchiveIntermediates/Infomaniak\ Mail/IntermediateBuildFilesPath/Mail.build/Release-iphoneos/Infomaniak\ Mail.build/assetcatalog_generated_info.plist_thinned --app-icon AppIcon --accent-color AccentColor --compress-pngs --enable-on-demand-resources YES --development-region en --target-device iphone --target-device ipad --minimum-deployment-target 15.0 --platform iphoneos Has anyone encountered a similar issue ?

Some of my apps are configured to use Xcode Cloud. Some time ago, this service was blocked for developers from Russia. I want to transfer one of my apps to another account. But there is the following requirement in the checklist: "You must remove all Xcode Cloud related data from the app you want transferred." I can't do it myself because I see an error in App Store Connect: "The page you’re looking for can’t be found.". It is also not available through Xcode. I would like to delete all Xcode Cloud settings for all my apps. Can you help me with this?

We would like to request an enhancement to Xcode Cloud workflows to support skipping builds when a GitHub Pull Request is in Draft state. Our team frequently collaborates on pull requests that go through multiple iterations during the code review cycle. Each small commit or push triggers an Xcode Cloud workflow run, even if the PR is still in draft and not ready for final review or CI validation. This leads to: Wasted compute resources and time on draft work that is not yet intended for integration. Increased noise in Xcode Cloud logs and dashboards. Longer feedback cycles for meaningful PRs, since draft workflows compete for available concurrency. A simple option in the workflow configuration (e.g., “Skip runs for draft pull requests”) would address this problem by: Reducing unnecessary workflow executions. Freeing up capacity for production-ready and review-ready builds. Improving overall developer productivity by aligning CI runs with the actual readiness of a PR. This feature would be especially valuable for teams with frequent collaboration and long-lived PRs. Thank you for considering this request—we believe it would significantly improve the efficiency of Xcode Cloud for real-world development workflows.

Hi I have an developer app tied that is the account owner for our ABM and also for our Apple Developer account. When i go to the developer app and try to purchase additional hours it doesnt let me "Apple account cant be used to make purchases" And i am the account holder for both. The email tied to it is an "username/@/domain.appleid.com". Any help appreciated

So my xcode cloud build have been stuck for 12 hours, is there something wrong with me or the service isnt working rn?

Hi Apple DTS & community folks, I’m reaching out regarding an issue we’ve encountered with the com.apple.developer.mail-client capability for our app (bundle identifier: so.notion.Mail). We were granted this entitlement last week to allow the app to be set as a default Mail client. While everything works as expected when archiving and distributing builds locally in Xcode, we’re running into a problem when using Xcode Cloud. Specifically, Xcode Cloud attempts to archive and distribute an Ad-Hoc build, but the Ad-Hoc provisioning profile does not include this special entitlement. Since we’re using Xcode-managed profiles, we don’t have the ability to create or adjust an explicit profile ourselves. This issue only arises in Xcode Cloud—local distribution works unless we explicitly attempt an Ad-Hoc build (which is not our intent). I’ve included a screenshot of the error for reference. We found this forum post describing the same issue, where the resolution was Apple enabling the entitlement for Ad-Hoc builds. We’d like to request that Apple enable this capability for Ad-Hoc builds for the Notion Mail application so that Xcode Cloud distribution functions correctly. Thank you for your help!

We have a simple workflow that just runs the Test action on my unit_tests scheme (see Xcode Cloud workflow configuration screenshot). The workflow is configured to use Xcode 16.4 (Latest Release), macOS Sequoia 15.6 (Latest Release), and iOS 18.0 simulators. Today, this workflow has been consistently running indefinitely. The Xcode cloud runner tries to launch the simulator to execute the tests, but it fails. See the error message in the screenshot from Xcode Cloud logs. Link to corresponding build is in my Feedback Assistant ticket. It continues to retry this operation for a very long time — I had one job that ran for over 90 minutes. Link to corresponding build also in that same Feedback Assistant ticket. Are Xcode Cloud runners perhaps currently undergoing maintenance? Or is something else going on. I would appreciate if Xcode Cloud usage from today could be refunded to my team’s account. Feedback Assistant ticket #FB20195292. Error message: MyApp encountered an error (Failed to prepare device 'iPhone 16' for impending launch. (Underlying Error: Unable to boot the Simulator. launchd failed to respond. (Underlying Error: Failed to start launchd_sim: could not bind to session, launchd_sim may have crashed or quit responding)))

Xcode 26 RC is not available on Xcode Cloud. This is a serious blocker affecting developers trying to be on App Store on day 1 of the OS 26 release. Is there an estimate when this can be in place?

I cannot setup a workflow - every time it says "This operation could not be completed" after granting access to the source code. I removed the app from AppStore Connect, I logged out from Xcode, removed and reset the app from Github, initialized a new repository, reset Xcode Derived Data, reset the Profiles and Certificates. I tried everything and nothing worked. Any help?

I have now signed out of my account in Xcode, quit the application, signed back in, and also cleared the Xcode derived data and cache.

I've been getting intermittent failures on Xcode code compiling my app on multiple platforms because it fails to compile a metal shader. The Metal Toolchain was not installed and could not compile the Metal source files. Download the Metal Toolchain from Xcode > Settings > Components and try again. Sometimes if I re-run it, it works fine. Then I'll run it again, and it will fail. If you tell me to file a feedback, please tell me what information would be useful and actionable, because this is all I have.

Hey, We're crunching to get our products ready for the announcements next week but are being slowed down by Xcode Cloud. Builds are failing and are extremely slow. We're using the latest Xcode beta and latest macOS release so we can upload our builds continuously to TestFlight. We're seeing builds taking up to almost an hour, even though takes around 10-15 minutes when it doesn't fail. The errors we're seeing seem to be timeout, for example: Showing All Errors Only The step invocation hit a user timeout. The xcodebuild build invocation timed out. No activity has been detected on stdout, stderr or the result bundle in 30 minutes. Here are links to some builds which have been restarted multiple times but keep failing for reasons out of our control. Please advice on how to get unblocked. https://appstoreconnect.apple.com/teams/69a6de80-3540-47e3-e053-5b8c7c11a4d1/apps/1102236212/ci/groups/8da12ae3-b454-4810-abe8-829f1af56a54 https://appstoreconnect.apple.com/teams/69a6de80-3540-47e3-e053-5b8c7c11a4d1/apps/1102236212/ci/groups/ee7b1fae-1363-4265-9d64-692434b7ebf2 https://appstoreconnect.apple.com/teams/69a6de80-3540-47e3-e053-5b8c7c11a4d1/apps/1102236212/ci/groups/fd915140-db2c-4b3b-bff4-16939c22665a

I've been running into issues with Xcode Cloud/my workflow when it's trying to archive the app. I've tested locally and both archiving and building the app for release works. I've tried a few things to clear it. pod deintegrate and pod install Checking off "archive" for the build scheme Creating a certificate for both development and distribution. I made sure automatic signing was enabled as well. I have a ci_scripts/ci_post_clone.sh script that successfully completes. Have tried setting the xcode version of the workflow to 16.2 which is what my local xcode version is. I've switched it back to the latest, 16.4. running pod update Updating flutter However, I consistently get the following 2 errors : `Showing All Messages Run command: 'xcodebuild archive -workspace /Volumes/workspace/repository/ios/Runner.xcworkspace -scheme Runner -destination generic/platform=iOS -archivePath /Volumes/workspace/build.xcarchive -derivedDataPath /Volumes/workspace/DerivedData -resultBundleVersion 3 -resultBundlePath /Volumes/workspace/resultbundle.xcresult -resultStreamPath /Volumes/workspace/tmp/resultBundleStreame3592434-5b88-48da-a3c4-f750abee4d08.json -IDEPostProgressNotifications=YES CODE_SIGN_IDENTITY=- AD_HOC_CODE_SIGNING_ALLOWED=YES CODE_SIGN_STYLE=Automatic DEVELOPMENT_TEAM=JG794CQD68 COMPILER_INDEX_STORE_ENABLE=NO -hideShellScriptEnvironment' ` and Showing All Messages Unhandled exception: ProcessException: No such file or directory Command: /Users/local/flutter/bin/flutter assemble --no-version-check --output=/Volumes/workspace/DerivedData/Build/Intermediates.noindex/ArchiveIntermediates/Runner/BuildProductsPath/Release-iphoneos/ -dTargetPlatform=ios -dTargetFile=lib/main.dart -dBuildMode=release -dConfiguration=Release -dIosArchs=arm64 -dSdkRoot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS18.5.sdk -dSplitDebugInfo= -dTreeShakeIcons=true -dTrackWidgetCreation=false -dDartObfuscation=false -dAction=install -dFrontendServerStarterPath= --ExtraGenSnapshotOptions= --DartDefines=RkxVVFRFUl9WRVJTSU9OPTMuMzUuMQ==,RkxVVFRFUl9DSEFOTkVMPXN0YWJsZQ==,RkxVVFRFUl9HSVRfVVJMPWh0dHA6Ly9naXRodWIuY29tL2ZsdXR0ZXIvZmx1dHRlci5naXQ=,RkxVVFRFUl9GUkFNRVdPUktfUkVWSVNJT049MjBmODI3NDkzOQ==,RkxVVFRFUl9FTkdJTkVfUkVWSVNJT049MWU5YTgxMWJmOA==,RkxVVFRFUl9EQVJUX1ZFUlNJT049My45LjA= --ExtraFrontEndOptions= -dSrcRoot=/Volumes/workspace/repository/ios -dTargetDeviceOSVersion= -dCodesignIdentity=- release_ios_bundle_flutter_assets #0 _ProcessImpl._runAndWait (dart:io-patch/process_patch.dart:519:7) #1 _runNonInteractiveProcessSync (dart:io-patch/process_patch.dart:686:18) #2 Process.runSync (dart:io-patch/process_patch.dart:79:12) #3 Context.runSyncProcess (file:///Users/local/flutter/packages/flutter_tools/bin/xcode_backend.dart:154:20) #4 Context.runSync (file:///Users/local/flutter/packages/flutter_tools/bin/xcode_backend.dart:118:34) #5 Context.buildApp (file:///Users/local/flutter/packages/flutter_tools/bin/xcode_backend.dart:539:34) #6 Context.run (file:///Users/local/flutter/packages/flutter_tools/bin/xcode_backend.dart:51:9) #7 main (file:///Users/local/flutter/packages/flutter_tools/bin/xcode_backend.dart:17:5) #8 _delayEntrypointInvocation.<anonymous closure> (dart:isolate-patch/isolate_patch.dart:312:33) #9 _RawReceivePort._handleMessage (dart:isolate-patch/isolate_patch.dart:193:12) Command PhaseScriptExecution failed with a nonzero exit code Any help here would be greatly appreciated.
