Create a remote source code repository when you want to access your project from another Mac, back up your project on a server, or share your project with others.
In the Source Control navigator (), Control-click the repository, then choose “Create [Project] Remote” from the pop-up menu.
If necessary, choose the remote account or “Add an account” from the Account pop-up menu.
Note: If you add a remote repository account in Account preferences, you won’t need to enter this information again.
Optionally, enter a repository name that is different than the project name.
Enter a description of the repository in the text field.
To allow public read access to the repository, select Public; otherwise, select Private.
Click Create.
Xcode commits and pushes the changes to the server.
