I was able to fix this by registering Xcode with Launch Services again:

$ /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -f /path/to/Xcode.app

I think this happens if you confuse Launch Services by switching between multiple copies of Xcode.

I encountered the same problem, who knows how to solve it?

[saagarjha]

Did any of the solutions posted in this thread help?

[kunlongxu]

I tried a few times but nothing worked. I also tried to install other plugins, but the xcode option didn't appear. @saagarjha

[saagarjha]

Can you try this and send me to the output? If that doesn't work, can you try registering all of the Xcodes you have on your machine and trying again after that?

[kunlongxu]

pluginkit -vmAp com.apple.dt.Xcode.extension.source-editor
(no matches)

How to register all of the Xcodes? @saagarjha

[saagarjha]

Just run the lsregister command I mentioned above repeatedly with the path to your Xcode substituted in where specified.

[kunlongxu]

first:
lsregister -u /Applications/Xcode.app
after:
lsregister -f /Applications/Xcode.app

not work

[kunlongxu]

I install only one Xcode App.

Can confirm @saagarjha method is working however I will monitor over the coming days as the issue seems to come and go in the past as I restart my computer. Hopefully this fixes it.

Both installing version 1.6 from my closed issue and this worked:
