Learning Core Data for iOS: A Hands-On Guide to Building Core Data Applications

1. Your First Core Data Application

If you can’t explain it simply, you don’t understand it well enough.

Albert Einstein

Kinesthetic learning, or learning by doing, is one of the best ways to absorb and retain information. The topic of Core Data has been a great hurdle for many seasoned programmers, so it’s about time a book with a hands-on approach to Core Data was written. In order to avoid side tracking into deep topics too early, this chapter has many pointers to later chapters. First things first: It will give you a Core Data essentials primer, then dive right in and show how to add Core Data to the sample application. The sample application will be expanded over the course of this book as increasingly advanced topics are introduced.
