XCode 8 Comment out broken [duplicate]

Question

On XCode 8 Beta 5 & 6 cannot use the comment out functionality. Seems it is disabled in the context menu and shortcut does not work.

I have submitted this to Apple via bugreport.apple.com and got a response that it has already been reported. I am on Mac OS 10.11.6

Does anyone know how to fix this?

I had this issue with the Xcode 8 GM version. I just moved Xcode 8 into another directory and opened it again. Then it works.
