Re: Xcode 8 beta 4 - Comment/Uncomment broken

Same problem here (Cmd-/ not working, it's grayed out in the menu). My colleague has same Mac / OS, but it works for him.

If anyone finds a workaround -> Please share! Thx.

Same problem.   10.11.5 (15F34)

If anyone finds a workaround -> Please share! Thx.

I rebooted, now it is working.

When I started beta 4 it asked me to "install required components" a second time.   Don't know if related or not.

"Some systems" includes my 2012 mac mini. too

I wonder if there is some file or cache we can delete to get this working again.

So Xcode 8 beta-5 is out today, in the release notes there is this:

Appears to working correctly now under Xcode 8 beta 5. Was broken for me under beta 4.

Xcode beta 5 line comment still not working for me either.

Xcode 8 beta 5, menu comment uncomment still gray, and can't find the enable preference for it, if there is the preference for it;

And I don't quite get it when the Xcode 8 beta 5 documentation says when you enable it, since the Xcode 7  I never set it and it worked well.

Does not work for me either, and I cannot find the option to turn it back on. I agree with @yellowsubmarine it is hugely inconvenient. You get used to using short cuts and when they don't work your whole work flow gets pulled out of sync. Please chime in Apple and let us know how to re-enable this option.

Aaaaaaaand still a no-go on beta-6. *sigh*

Submitted Apple bug report 27855179.

In Xcode 8 beta 6, the comment / uncomment still gray

El Capitan 10.11.6

Installing OS X 10.11.6 seems to fix this issue

Still not fixed, but some dude on Twitter that I shall call a hero found a workaround. Worked for me. I can't type it here because Apple forums keeps giving me "post contains invalid characters". But here's the tweet:

I'm on Xcode 8 Beta 6. The comment/uncomment shortcut was working on this Beta version for me for awhile, but today it is not working for me, and the Moskowski fix didn't work either.

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.

The Xcode 8 GM has a fix for this. From the release notes:

Source Editor Extensions

• To use the Editor's Comment/Uncomment Selection and Add Documentation commands—as well as other installed Xcode Extensions—on OS X version 10.11, launch Xcode and install additional system components, then restart your Mac. (26106213)

Looks like the additional system components installer script does xpccachectl on El Cap.

I was having the same issue in Xcode Version 8.0 (8A218a) with OSX 10.11.6 (15G1004)

I just reboot my MacBook and now it is working.

Ugh!  Mine has quit working too and it is driving me freaking nuts!

First Apple kills Alcatraz, now this! 

C'mon Apple!!!

It is fixed (for me) in Xcode Version 8.1 (8B62).

Still broken under xcode 8.2 lol. looks like xcode as less and less bugfix and more feature. I would hope apple would take the time to fix bug before they add features. Some bugs have been here since xcode 6.

I've noticed in xCode Preferences | Key Bindings | All,  that there are multiple binings showing up if you search fro CMD+/

One of them was blank after the search so I just replace it with the key sequence cmd+/ and now it works. I had tried the thing from twitter above and it didn't seem to work for me.

Using Xode 8.1 (8B62). Hope it helps somebody if it works...

While working on moderately to large sized C++ projects, I have also noticed that the comment toggle ( ⌘ / ) intermitently stops working, even when all the key bindings are enabled, and the function is not greyed-out in the Editor → Structure → Commnent Selection.

I realized that it only happens for specific source files. If you have multiline /* ... */ comments, it is possible that they overlap, are nested, or not properly closed. This probably confuses the parser that the editor is using. The problem is resolved by deleting the messy, commented-out code. Running a Build Clean also seems to help.

I'm not sure if this is the same problem being discussed here, but I thought I might add my experience.

This appears to be still broken at Xcode 8.2.1 (os 10.12.3): sometimes the comment shortcuts stops working and I have to restart XCode.

This is very annoying and doesn't look like something that should take that long too fix -- this should be a P0 for the xcode dev team to fix.

God, Mine too.

Xcode 8.2.1 (8C1002) OSX Captian 10.11.6

Comment/Uncomment is broken. I tried sudo /usr/libexec/xpccachectl,but it doesn't work.

And even I have no nested comment neither blocked comment the menu is still grey. Could anyone help me? It's really a big problem.

This solution worked for XCode Version 8.2.1 (8C1002) not beta under macOS Sierra.

" Try this. I tried the suggested terminal command + restart many times and it didn't work, but this did. Go to your applications folder and rename Xcode to whatever you want, then open the app. Check to see if the comment selection now works, if so, you can go back and rename Xcode to its default name. If not, then keep searching for another method. "

Still happening for me on:

Version 8.3.2 (8E2002)
