Xcode 9.4 : Error generating code coverage


I'm running all test cases of project (cmd + U) then all of sudden this error message pops-up with no reason. I'm using Xcode 9.4.

Any fix?


Solution

  • Is is possible you are running on device and it is locked?

    The same thing just happened for me ("Error Generating Code Coverage" when trying to run all tests) and then I realized that Xcode was trying to build to my phone, which was locked. It ran ok on my phone after I unlocked it (and fine on the simulator as well).
