Hello,
Since 21 October 2026 at about 16:07 UTC, every Xcode Cloud build for our team is cancelled 5–6 seconds after it starts. This happens across two products, two GitHub repositories and every workflow. Before that date Xcode Cloud worked normally, and we have used roughly 11 of our compute hours.
What happens
• A build is created, then marked COMPLETE / CANCELED about 6 seconds later.
• startedDate is null, cancelReason is null, and there are no actions, no logs and no builds.
• It happens whether the build starts from a push, from the App Store Connect website or from the App Store Connect API.
• It happens with the simplest possible workflow: one Archive action on "Latest Release" (Xcode 27.2, 27B52, and macOS Golden Gate 27.2, 26B123). Specific Xcode versions (27.1, 27A9275) fail the same way.
• Product 1: runs #99–#105 were all cancelled. The latest are #104 and #105 on 15 Nov 2026.
• Product 2: runs #136–#140 were all cancelled, across several days from 23 Oct 2026.
Other symptoms
• appstoreconnect.apple.com/xcode-cloud shows a blank white page, in normal and private windows, in more than one browser. The app pages in App Store Connect show no Xcode Cloud tab.
• In Xcode on my Mac, the Xcode Cloud screens say "Unauthenticated", even though I'm signed in to my developer account in Xcode. The Mac is a MacBook Pro (15-inch, 2017), macOS Ventura 13.7.8 (22H730), Xcode 15.2 (15C500b). We don't build on this Mac; it only manages Xcode Cloud.
• scmRepositories.lastAccessedDate stopped updating at 21 Oct 2026, 15:57 UTC for one repository, minutes before the cancellations began, and now returns null for both repositories.
What we've already tried
1. Reinstalling GitHub access: uninstalled and reinstalled the Xcode Cloud GitHub app with access to all repositories, and re-granted access. No change.
2. Confirming Apple can see the code: the App Store Connect API still lists our branches and commits, and Xcode Cloud shows the right commit message on each cancelled build.
3. Removing extra workflows: removed every workflow except one plain Archive workflow. Still cancelled.
4. Checking the account: the developer membership is active, and all agreements in App Store Connect are accepted.
5. Checking uploads elsewhere: builds made on another CI system (GitHub Actions, Xcode 26.6) upload to TestFlight and pass App Review submission normally on the same account. Only Xcode Cloud is affected.
6. Checking Apple's System Status: shows no Xcode Cloud problems.
7. Contacting Developer Support: case 103005804006. Support pointed us to the forums.
One possible trigger: on 21 Oct 2026, between 15:52 and 16:53 UTC, we created three new test workflows through the App Store Connect API. Their test destinations included an iOS 17.5 simulator alongside Xcode 27 and a newer-device simulator on iOS 27.1. The cancellations began minutes later. We have since deleted those workflows, and builds are still cancelled.
Our question: it looks as if our team's Xcode Cloud setup on Apple's side is stuck or broken, which would explain both the blank page and the instant cancellations. Could someone on the Xcode Cloud team check our account and reset it? I'm happy to share the team ID and build run IDs privately.
Thank you.
