Have your Xcode Extensions ever just… disappeared on you (usually after a crash)?

They’ll be completely missing from the Editor menu item in Xcode itself, but also missing from the Extensions area of System Preferences.

Well you’re in luck, I have a simple solution for you.

  1. Quit Xcode Completely
  2. Go to /Applications (where Xcode.app is installed)
  3. RENAME Xcode to something (I usually just add a space before “.app”) and hit Enter
  4. Revert Xcode to it’s original name.
  5. There is no step 5.


From Xcode​Kit and Xcode Source Editor Extensions on NSHipster:

when multiple copies of Xcode are on the same machine, extensions can stop working completely. In this case, Apple Developer Relations suggests re-registering your main copy of Xcode with Launch Services…

That’s all we’re doing when we rename Xcode, we’re simply re-registering it with Launch Services.
