        This crash is only happening on XCode 11.4, if code coverage is enabled. If code coverage is disabled it works fine, but we want the code coverage after executing unit tests. In Xcode 11.3 unit tests were executing fine with the code coverage enabled. Could any one please let us know the solution for this issue. Thanks in advance.

         

        Thanks,
