Source Control

The new top-level Source Control menu always shows the currently active branch of the project you are working on, and gives you quick access to switch, create, and merge branches. You’ll never need to leave your code to create a new feature branch, or fix a bug. If you don’t remember writing the code in front of you, you can check who to blame for that line, right in the editor. The new Accounts preference in Xcode gives you a single place to manage all your repositories, and OS X Server for OS X Mavericks can even host Git repositories for you and your team.
