This continues to be an issue on Xcode 12.1. I've reset my Xcode Server using sudo xcrun xcscontrol --reset and setup a new bot. Still receiving the same 'export archive' errors noted above. I've attached another diagnostics file to FB7505463.

Xcode 12.3, same results: FB8965234 All iOS & tvOS Integrations do not produce installable product and present the export archive failure.

Xcode Server exists as a part of the Xcode app, so you can't remove it... but you can reset to a state where it is not configured. Swift 'Off' Xcode Server in the Xcode preferences. In terminal, run sudo xcrun xcscontrol --reset Remove the Xcode Server account in the Users system preferences.

I seem to be experiencing the same. iOS deployment target of 13.4, running on a 13.7 simulator. With the .compact preferred style set, the date picker continues to display the .wheels style components.

I guess this no longer matters. Xcode 14 official deprecated Xcode Server.
