Having coded, designed, debugged, and tested your application, it would be a disaster if something were to happen to it. But it’s not external threats you need to worry about; the greatest danger to the well-being of your app is you. Failing to back up your code means you risk being wiped out with a single hard drive failure.

But that’s only one possible risk. What if you go on a late-night tear through your code — born of inspiration and optimism — only to wake up the next day with an app that won’t build, no less run, and not enough undos in the world to get you back to a state where it worked? At this point, you’re out of luck.

Any professional development requires the use of source control management, the formal system of tracking changes in your codebase. Properly used, good SCM practices will save you from disasters, help you understand the history of your work, and facilitate working with others.

Xcode has fairly deep support for Git, the mostly widely used source control system today. In this chapter, you’ll see how it integrates with Xcode, what it does for you, and why you sometimes may need to go outside of Xcode for advanced features.

While this chapter introduces SCM concepts gradually, it’s not meant as a complete introduction to either SCM generally or Git specifically. For that, check out Pragmatic Guide to Git [Swi10].
