Creating a git repository for an existing Xcode project ∞
Ash:

New Xcode projects will let you keep local git source control. Using an existing project with this local source control is … difficult. I tried for a while before almost giving up. Documentation around the “Add Working Copy” is almost non-existent. This is how you do it.

Alternatively:

$cd path/to/project
$git init
$git add .
$git commit -m “Initial commit of project”
Keep in mind with either approach, it’s a good idea to include a good .gitignore file. Here’s a good one for Xcode projects.
