Multiple line comment in Xcode 8

Question

I just upgraded to Xcode GM 8.0 and noticed ⌘ + / is not commenting out selected lines. Is there another command to comment out multiple lines in Xcode 8?

Answer 1

I finally figured this one out, drove me crazy…

These are the preconditions for the bug to arise:

1. '/' needs to be accessed with the shift key, like i.e. on German keyboards.
2. There is a global OS X hotkey to access help with shift+cmd+'/', which is the default

Under these preconditions there is not conflict showing in XCode keyboard preferences, but it trying to invoke cmd+'/' triggers the global help hotkey anyway.

How to fix it?

Simply remap or switch off the global hotkey to show help in system preferences > keyboard > keyboard shortcuts, select app shortcuts in the list on the left.
