How to use GitHub repositories in XCode

[Video]  XCode has built-in version control that uses git to store your project and its code at every step in its development process.  If anything goes wrong, you can easily revert your code to a previous working version.  If you want to try something new, you can create a branch to test your idea to see if it works before committing it the the main "master" line of revisions.
Git is known for its distributed version control.  This means that it works well in a centralized hosted manner as well as a local manner and it works with or without a reliable internet connection.  Its flexibility makes it useful in nearly every context of files that change over time.
You can use XCode's version control to its fullest extent by using GitHub as a central server to host your git repository (as opposed to on your local computer).  This frees your code by putting it into a public repository with some social features to let you share your code and show off your projects.
I created a screencast video that explains how to set up a GitHub account and connect it with your XCode projects.

I hope it helps you get more out of XCode.
