How to configure Xcode with BitBucket

If the project folder is already on your computer, and is already under git control, skip this first step. Otherwise, use the command line, or Xcode's Source Control > Clone dialog, to clone your bitbucket repo onto your computer.

Open the project in Xcode and work with it.

There is no step 3! Xcode will see that this repo is under git control and you'll be able to use Xcode's built-in source control features as usual.
