After completing this learning path…

…you’ll have covered a lot of ground, by getting “behind the scenes” and learning about all the options for persisting data in iOS apps, and when to use each option. You’ll have learned how to work with data over the network with REST APIs, and how to offload intensive processing to background threads. Check out the iOS IDEs and Tools path to learn how to use Xcode like a pro, how to debug your apps, and how to get your app up on the App Store for the world to enjoy!

Coming Up Next: As a professional developer, you’ll spend most of your time immersed in Xcode, so it’s worth learning how to love your main IDE! The next learning path will take you from Xcode novice to poweruser, so you can accomplish more coding and debugging — and less time fighting with Xcode. Plus you’ll learn all of the ins and outs of submitting your app to the App Store!
