Today I updated to Xcode 6.3.2 and I can't run the Clang code formatting – it seems like it's not even installed. Everytime I update Xcode, I have to reinstall Alcatraz and most of the packages (why btw?) to make them work on the new version of Xcode.
This time I reinstalled all packages (like VVDocumenter, Color picker, etc), but the ClangFormat doesn't work – it doesn't even appear in the "Edit" menu. Any idea why?
btw. I tried to restart Xcode as well as the Mac itself :)
EDIT (Solution):
Solution for Xcode 6.3.x (If this does not work, use the general solution below.)
In terminal, enter the following:
find ~/Library/Application\ Support/Developer/Shared/Xcode/Plug-ins -name Info.plist -maxdepth 3 | xargs -I{} defaults write {} DVTPlugInCompatibilityUUIDs -array-add 9F75337B-21B4-4ADC-B558-F9CADF7073A7
General solution
Get the new UUID via the terminal:
defaults read /Applications/Xcode.app/Contents/Info DVTPlugInCompatibilityUUID
Add the new UUID to the DVTPlugInCompatibilityUUIDs key in the plugin (your xcplugin file --> show package contents --> Contents/Info.plist
