Xcode 7.3.1 and the Vanishing Unit Tests

I updated to 7.3.1. I have a XCTestCase with 10 or so test methods. Everytime I run the suite the Test Navigator status display of tests goes down by one. The source file still has the code, just seems that XCode is losing track of them. If I add a new test case it doesn't find it either.


Worked as expected before the upgrade. Anyone else notice this or have a fix?
