XCode 8 Comment out broken

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?

In Terminal: sudo /usr/libexec/xpccachectl

Reboot.

Answer 2

You aren't, by some chance, commenting out the second line of a multi-line macro, are you? If so, I already filed a bug about it, and it was broken in Xcode 7, too.

Otherwise, the way you fix it is to

• File a bug report at bugreport.apple.com
• Roll back to a previous version (or just ignore it and manually comment out the lines)

Xcode 8 might not be fully supported by el captain, i couldn't make comment on el captain but now i can make comment when i updated my os to developer beta 7.

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.
