I'm having the following error when trying to run the tests for my Swift/Obj-c app:

It's a fairly big app and it does not use Frameworks as I need to support iOS 7 if that makes any difference. The app had no tests. I have just created the first test suite now.
After hitting my head a few times over this, I decided to delete the test target and recreate it from scratch. that solved my problem.
