If I choose an XCode 15 environment in XCode Cloud, this changes nothing. Still I receive this error.

I've tried: Removed the LSMinimumVersion key from info.plist or tried several version numbers. Tried several macOS deployment targets under Targets > Deployment Removed the libswiftCloudKit entry from "Targets>Build Phases>Link Binary with Libraries" and "Targets>General>Frameworks" Tried a lot of funny environment combinations in XCode Cloud, including (of course) going back to a former XCode version. Nothing helps. Users are getting angry.

Guess what, it's not working either here again. Seems to have been a one-time success... whatever.

I'll try - never thought that this level of personal communication would be possible :-)

There isn‘t any yet, that‘s the problem.

Worked for me, but I dont know why.
