Once we have a repository, we can checkout a project:

1. Open XCode.
2. Go to SCM -> Repositories.
   1. Select your repository.  You will see the wait animated icon on the bottom right corner of the window...so wait a bit.
   2. Navigate to the folder that contains your project (*.xcodeproj file).
   3. Hit the Checkout button.
      1. Select the folder on your local machine where you want to check out this folder.
      2. Hit the Checkout button.
   4. More wait animated icon...more waiting...this may take a while because it's bringing down all the files and folders.
   5. You will be prompted to open the project or continue.  Open the project.
   6. Go to Project -> Edit Project Settings.
      1. Down at the very bottom, select the proper SCM Repository in the drop down.
      2. Close your Project Settings window.
   7. You may see your SCM folder on the left do the wait animated icon now.  That icon is pretty popular.
      
   8. Select the SCM icon on the left.
   9. You will now see a lot more options under your SCM menu.  You will also see any new or modified files in your file list when you select the SCM icon.
