One additional benefit of Github to the ones NotMyName and KMT listed is online backup of your code. Without Github if your Mac was stolen, was destroyed in a fire, or had its hard drive/SSD go bad, you would lose your code. With Github if disaster strikes, you can buy a new Mac, clone your Github code on the new Mac, and continue to work on your app as if nothing happened.
