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!

Hi VerticaTKC, We've made some improvements in this area of Xcode Cloud. Please let us know if you're still experiencing the issue.

Hello, I am having this same issue. I typically run my builds on latest XCode release and latest OS version, but I also tried setting the workflow to an earlier version in case there was an issue with XCode 16, but I get the same error in both cases: "Failed to download iOS 16.1 simulator runtime"

Is there anything I can do on my end to fix this, or is this purely an XCC issue?

Same issue here can't see iOS17 simulator and can't install iOS16. Also test in iOS18 are not working we are getting a time out after 10 minutes, I think is because when trying to run the tests the simulator is asking for some permissions.
