The coverage of a lot of modules inside our iOS App, not all of them. it appears to be broken since Xcode 16.2
There are some reports over internet without any fix https://www.reddit.com/r/iOSProgramming/comments/1jnzgxw/tests_coverage_not_visible_on_xcode_162/
there's an error message in the logs:
raw profile version mismatch: Profile uses raw profile format version = 8; expected version = 10
Xcode 26 didn't fix the issue as well
