Experiencing the same issue with my project. I have 4 XCFrameworks in my code. If I compile 5 times, it gets past the ProcessXCFramework errors, but then of course it fails finding headers after that. It basically once for each framework. I believe it is looking for the .a file of the library, which gets copied correctly, before it moves on to the next one.

Same issue here. I noticed it today as I was about to submit a build to Test Flight. I've also sent off a support email to hopefully get more notice. This seems to be a backend issue.

I received a support response with a generic "have you looked at our code signing help documents" response. I have pushed back in my response explaining this is either a bug with Xcode or their backend.

Attempted upgrading from 14.0 to 14.0.1. No change. Support ultimately told me to use Feedback Assistant, so I've submit a request in there as well.

I can also confirm it happens on every computer I have Xcode installed on. It's something specific with the account, as my other accounts in Xcode load just fine.

As of right now, this seems to be working again. I was able to load my profile in Xcode Preferences and submit builds directly to App Store Connect.
