Luckily our app has an tvOS target as well and there the coverage is working. Some test code, same implementation code, I simply added the tvOS target membership for our test files.

Same issue here. I figured out that initialisation of AVPlayerLayer() in our code causes the issue. Xcode 13.3

I've found the solution after playing around in gitlab settings for a while. Simply uncheck the Confidential option in User Settings -> Applications.
