If you wanna improve it make a pull request on the gist

Pull requests are only possible on repos, not on gists.

    print('Authenticated!' if success else ObjCInstance(error))

Fixed spelling on Authenticated.

Yeah, sorry about the pull request, i dont use repos very much :-)

I have improved the script to handle more errors and options and @omz made a fork with exeptions and module style script

This is supercool functionality. A great idea.

A repo would keep us all focused on the latest and greatest version instead of forked gists that Can become out of sync with each other.
