Banging my head against my desk... 6.3 introduced some issue (it was in the beta release notes) that prevented Xcode from being able to correctly index my tests, and therefore all of my tests are being found at runtime. I have 1000+ tests and the only way to run them is to CMD+U to run them all. It's very annoying when I am targeting a specific issue and slows down my development immensely. Anyone have any suggestions to work around? Any one else feel my pain?
