问题
I have setup a unit test for my project. Initially i got stuck with errors during the compilation of the test file, finally i solved it and my tests now are working.
The problem now is that the syntax highlight is not working for the test file, only for that. I tried following this answer to solve this issue but no luck. Removing the derived data of the project worked one time but then i closed xcode and when i reopened it there was no syntax highlight again. Also i have reinstalled xcode 5 from App Store 2 days ago so this should be a fresh new install. Can you help me?

For me this issue went away when I added my Test target to the Test action in the Scheme editor (Product->Scheme->Edit Scheme..).
