Xcode Cloud build phase has massively slowed down
Hi, recently something happened in Xcode Cloud, and the build times increased massively. In our CI workflow we run test, and one of the phases executes xcodebuild build-for-testing: the duration of this phase moved from about 8 minutes to about 36 minutes, without any major changes on our side. We observed this: in different apps; even when running a build on a old tag. All other phases don't seem affected, it's just the xcodebuild build-for-testing phase. I'm attaching 2 screenshots of the logs from AppStoreConnect that show the duration of each phase, where build 7600 is older and 7700 is more recent (but was run on a tag from a few weeks ago, to exclude issues related with the code base itself). We had not other option than to disable the CI checks for PRs, because they would take too long, and use up too much of Xcode Cloud time. What's happening? Thanks

Xcode Cloud fails to install/launch macOS test runner
When running a SwiftUI Multiplatform app in Xcode Cloud I'm getting the following error: CIWatcher encountered an error in CIWatcherTests failed with: Failed to install or launch the test runner. (Underlying Error: Could not launch “CIWatcherTests”. Runningboard has returned error 5. Please check the system logs for the underlying cause of the error. (Underlying Error: The operation couldn’t be completed. Launch failed. (Underlying Error: Launchd job spawn failed))) This runs fine on iOS and all those tests pass. The SwiftUI app on Mac is a menu bar app so I'm not sure if this could be the issue as it's not launching for some reason on the Xcode Cloud system? Maybe I need to add some run option to make this work? When run locally both iOS and macOS pass all the tests successfully

Export archive fails due to No signing certificate "iOS Distribution" found
We are encountering build failures during the following stages on Xcode Cloud: • Export archive for ad-hoc distribution -> fail • Export archive for development distribution -> fail • Export archive for app-store distribution -> fail Run command: 'xcodebuild -exportArchive -archivePath /Volumes/workspace/tmp/a603f613-f0a2-4053-9316-2f25ca93250d.xcarchive -exportPath /Volumes/workspace/adhocexport -exportOptionsPlist /Volumes/workspace/ci/ad-hoc-exportoptions.plist '-DVTPortalRequest.Endpoint=http://172.16.56.69:8089' -DVTProvisioningIsManaged=YES -IDEDistributionLogDirectory=/Volumes/workspace/tmp/ad-hoc-export-archive-logs -DVTSkipCertificateValidityCheck=YES -DVTServicesLogLevel=3' Error Command exited with non-zero exit-code: 70 2025-01-21T05:11:20.962717086Z error: exportArchive There is a problem with the request entity 2025-01-21T05:11:20.962756880Z 2025-01-21T05:11:20.962760011Z error: exportArchive No signing certificate "iOS Distribution" found 2025-01-21T05:11:20.962764378Z 2025-01-21T05:11:20.962767137Z error: exportArchive There is a problem with the request entity 2025-01-21T05:11:20.962771440Z 2025-01-21T05:11:20.962774232Z error: exportArchive No signing certificate "iOS Distribution" found The build process was functioning correctly until this morning with same branch. We also have verified that our certificates are valid and successfully uploaded to TestFlight using these certificates on the local Xcode environment. This appears to be an issue on the Xcode Cloud side as no significant configuration changes were made on our end.

Xcode Cloud: The page you’re looking for can’t be found.
We started seeing an access issue today when attempting to go to the Xcode Cloud tab in App Store Connect. When you navigate to https://appstoreconnect.apple.com/teams/:teamId/apps/:appId/ci we're seeing the following message: The page you’re looking for can’t be found. The page you’re looking for does not exist, or you do not have permission to view it. I am the account holder so it shouldn't be a permissions issue. Is there an ongoing outage or problem in Xcode Cloud? And, if so, where can I monitor this accurately?

Xcode Cloud builds are running very long, trying to launch simulator
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)))

Failed to prepare device
We are getting unreliable results on XCode Cloud tests. I'm not sure if it's related to the current service outage. I'm running a very simple XCTest UI suite, on some devices it succeds and it others it fails to start. I'm not getting a userful error message. MyApp-Runner encountered an error (Failed to prepare device 'iPhone 16 Pro Max' 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)))

Symbol missing when building in Xcode cloud with Xcode 16 beta and running on macOS 14.6
We have a cross platform app that we build with Xcode Cloud and distribute via TestFlight. We want to test builds with the Xcode Beta. So we have the following build environment: Xcode version: Xcode 16 beta 6 (16A5230g) macOS Version: macOS Sonoma 14.5 (23F79) Everything builds and submits to TestFlight fine. The App runs fine on iOS 18 beta and macOS 15 beta. But when attempting to install via TestFlight and launch the App on macOS 14..6.1 it crashes immediately with what appears to be a missing Foundation symbol. Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: Namespace DYLD, Code 4 Symbol missing Symbol not found: _$s10Foundation14NSDecimalRoundyySpySo0B0aG_SPyADGSiSo14NSRoundingModeVtF Referenced from: <CBEBC813-C7B6-3D8E-BE62-16F2EFFEB1FE> /Applications/MyApp.app/Contents/MacOS/MyApp Expected in: <2F87A303-430F-3EA5-9492-3033F4FEE64B> /System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (terminated at launch; ignore backtrace) Thread 0 Crashed: 0 dyld 0x7ff8139f687a __abort_with_payload + 10 1 dyld 0x7ff813a0f7f7 abort_with_payload_wrapper_internal + 82 2 dyld 0x7ff813a0f829 abort_with_payload + 9 3 dyld 0x7ff81399c2b5 dyld4::halt(char const*, dyld4::StructuredError const*) + 335 4 dyld 0x7ff8139994bd dyld4::prepare(dyld4::APIs&, dyld3::MachOAnalyzer const*) + 4099 5 dyld 0x7ff8139982e4 start + 1812 Is it expected that this should work? Is this a known issue? Is there any workaround for it? Should I file feedback or a DTS?

Xcode Cloud workflows are not being started (Pull Request Changes)
Any Xcode Cloud workflow with 'Pull Request Changes' as one of its start conditions has suddenly stopped working altogether. The workflow is never started. This issue seems to have begun within the last 48 hours. Removing the 'Pull Request Changes' start condition makes the workflows functional again. The test I just ran to confirm this: Created a new Xcode Cloud workflow Selected Start Conditions: 'Pull Request Changes' from/into any branch, when any files are changed Selected Test as the 'Actions' Created a pull request on my github repository The workflow was never started Added 'Branch Changes' to the Start Conditions, specifying branch-a under 'Custom Branches' Pushed to branch-a The workflow was never started Removed 'Pull Request Changes' from the Start Conditions Pushed to branch-a The workflow finally started Curious if others are having this issue? And if so, is there a timeline for when this will be resolved? I have confirmed that our Github actions are configured properly, and believe this is indeed an issue with Xcode Cloud.

Xcode Cloud + Xcode 16.0.0 + Test Phase Always Exceeds 2 hours
My team's Xcode Cloud build started timing out when we recently upgraded to Xcode 16.0.0. Specifically, the test build phase times out due to exceeding the 2 hour limit. The Test - iOS action could not complete due to an error. The error may not occur on rebuild. Build has exceeded the maximum allotted time. Each build can run for up to 120 minutes. If a build has not yet finished at this time, all incomplete actions will be cancelled. When running Xcode 15.4.0, the test build phase completed in roughly 45 minutes. It's also important to know that our test build completes in about 15 minutes when executing on one of our in-house Mac mini build machines (Apple Silicon). So the issue seems to be with Xcode Cloud + Xcode 16.0.0 and not our project. We have been burning through Xcode Cloud hours hoping that at some point Xcode Cloud will be fixed. The status page right now is all "green": https://developer.apple.com/system-status/ Is there a known issue with Xcode Cloud + running tests? We have combed through our project's Xcode Cloud logs and artifacts, but nothing jumps out as something on our end. Also, there is a large file named "Test Products for ", but we can't download it due to crashes/ errors: The Xcode IDE UI shows this file as 1.99GB Xcode crashes when attempting to download the file. The App Store Connect UI shows this file as ~1GB (possibly just omitting precision). An error response page is returned when attempting to download. Thanks in advance for any advice/ feedback.

Unable to download artifacts from Xcode Cloud
I just discovered that I can no longer download any artifacts from Xcode Cloud, whether from newly built workflows or previous ones. When I try to download in Xcode, it crashes immediately. When downloading from App Store Connect, it redirects to an HTML page with the following content. {"message":"You are not authorized to access this team’s resources."} I've already tried re-logging into my Apple account. Is anyone else experiencing the same issue?

Random exportArchive 70 Error Code When Using Xcode Cloud for Build
Recently, I’ve noticed that the Archive workflow on Xcode Cloud frequently fails randomly with the following error: ❌ Exporting for App Store Distribution failed. Please download the logs artifact for more information I’m not sure if this issue is on my side or if it’s related to Xcode Cloud itself. Has anyone encountered a similar problem?

UI Tests with mock server
I'm using Xcode Cloud for release builds and unit tests, and it works fine. Recently, I added some XCUITests, but to run it the way I need I started to use this mock server. Basically, the idea is you define before each test what responses you want to get for specific requests. It works like a charm locally. But if I want to run it in Xcode Cloud, it looks like the server has failed to launch. The mock server is a separately launched binary file. I think this is because this permission I get when launch it locally. So, my question is how to allow this kind of permission in Xcode Cloud to make my UITests works correctly? You can find a detailed instruction how server is launched on a github page I provided.

Failed to download iOS 16.1 simulator runtime
My workflow has been running tests on iOS 15, 16 and 17 for a long time now, but suddenly it started to fail for iOS 15 and 16. The error does not seem to be code related, since it is a Xcode Cloud failure saying: "Failed to download iOS 16.1 simulator runtime". The exact same issue is showing for iOS 15. It works as expected on iOS 17. I have also reported this in the Feedback Assistant: FB14855036 If someone knows a work-around for this issue, I'd be happy to hear about it!

Hello, I'm getting started for my project with Xcode Cloud since I upgraded to the macOS Sequioa Beta and Xcode 16 now refuses to archive builds for TestFlight. Somewhere very late in the build process I get the following error: realitytool requires Metal for this operation and it is not available in this build environment The log says this happens at: Compile Skybox urban.skybox My project uses RealityKit. How can I fix this issue? Thanks!

Unit Test Execution in Xcode Cloud Too Slow Since Xcode 16 Update
Hello Developers, I regularly use Xcode Cloud to run unit tests, but since the release of Xcode 16, the testing process has become significantly slower. I am seeking advice on how to improve the situation. [ Details ] With Xcode 15.4, unit tests took about 1 hour to complete. However, since upgrading to Xcode 16, the tests have not finished even after 2 hours. The blog post linked below also mentions significant overhead in running unit tests on Xcode Cloud, even with Xcode 15.4: https://dwango.github.io/articles/2024-07_nicoiphone_xcode_cloud/#%E3%83%86%E3%82%B9%E3%83%88%E5%AE%9F%E8%A1%8C%E6%99%82%E9%96%93%E3%81%8C%E5%A2%97%E5%8A%A0%E3%81%97%E3%81%A6%E3%81%97%E3%81%BE%E3%81%86%E5%95%8F%E9%A1%8C According to the blog, while reviewing the xcodebuild-test-without-building.log, it was observed that the time from start to finish was about 4 minutes. However, the overall “Run xcodebuild test-without-building” process took 23 minutes, with around 20 minutes of apparent idle time. It seems that the idle time has increased even further with Xcode 16, resulting in more than twice the testing time. [ Question/Request ] Is there any way to reduce the overhead when running unit tests on Xcode Cloud, especially with the increased overhead in Xcode 16? Any advice or solutions for improving the performance would be greatly appreciated. Best regards,
