    Try setting CLANG_ENABLE_CODE_COVERAGE = NO in your build settings for the target being tested and the tests themselves.

    This may not be helpful to anyone else, but I was hitting this when I had placed a exit(EXIT_FAILURE) in my code while refactoring a piece of code. I had assumed putting it in would crash the app right there and show me that it crashed there, but instead it was giving me this error and not showing where it had crashed.

    Xcode 11 beta 1:

    This is a known issue when attempting to use code coverage against simulator targets. You must either use a later beta or run coverage against a physical device.

    Cleaning my build folder eliminated the error for me. (Option-Shift-Command K.) I'm using Xcode Version 9.2 (9C40b). The error started when I added a set of images to my Assets.xcassets. After a full clean the error is gone.
