Thank you for sharing this. Consider using xcode-select rather than an explicit path to /Applications/Xcode.app. That will allow you to use the installed Xcode, regardless of whether it was renamed or if the app is installed in another folder.

# Include git command completion macros
xcodeGitCompletion=$(xcode-select -p)/usr/share/git-core/git-completion.bash
if [ -f $xcodeGitCompletion ]; then
  source $xcodeGitCompletion
fi

Thanks for the feedback! Yup, that is of course the correct thing to do in the name of portability.

And this is quite an old gist, I should probably update it to the equivalent for zsh since that's been the default for years now already. aaakshuly, I think this will work just fine with zsh too
