I think this is related to the automatic saving file feature. I noticed that sometimes if i save the file manually and build, it completes correctly, but if i don't save the file and let xcode do it, it will fail on the first build, and then on second try succeed. This is so annoying to be honest.

We are having the same issue. It's an impediment to the use of XCode cloud so we are switching back to Gitlab. Does anybody has any news on this? A workaround maybe?

Same for me. Got a lot of these.Let me know if you solve it.
