I have a problem that the Xcode IDE 6 doesn't detect my swift unit test cases correctly. When I run the unit tests, all tests were executed.
But in the IDE while editing the unit tests aren't recognized. I have to run the whole unit test suite in order to run a single test.
I couldn't figure out how I avoid this glitch.
Problem is solved. All I have to do is to launch the "Window -> Projects" window and delete the "Derived Data. After indexing all tests are working.
In the meanwhile apple is fixing the bugs in the Xcode 6.3 editor bit by bit.
