Unit testing with no success/failure indication for each of the unit tests

I'm writing some unit tests in Xcode 7.1.1 in Objective C. After running the tests (Command + U) I get the message "Test Succeeded" but there's no success/failure indication for each of the unit tests. I checked the Test navigator and the code itself but I can't see any indication.

For the sake of this question, I've created a brand new project with a simple test but I'm having the same results.

After some research I found that this problem is happening to other users: http://ift.tt/1PNbjra. Does anybody has any clue?

Thanks!
