Xcode 11 unit tests always fails

Unit tests always fails in Xcode 11 in my project. I try to run a test where I only do XCTAssertTrue(true). In the test log I get this message:

I have tried to clean build folder, setting the build system to legacy, restarting xcode, deleting all other tests and running just the test class without any test methods. All fails and produce this error.
