In this book, you'll master Core Data in iOS using Swift. Comprehensive coverage of Core Data, from beginner to advanced topics.
This book is for intermediate iOS developers who already know the basics of iOS and Swift development but want to learn how to use Core Data to save data in their apps.
Start with with the basics like setting up your own Core Data Stack all the way to advanced topics like migration, performance, multithreading, and more!
Since UIKit is an object-oriented framework, you’re probably storing data in objects already. Core Data builds on this to keep track of the objects and their relationships to each other. You can imagine expanding the graph to include what the user ordered, ratings and so on. Persistence means the data is stored somewhere durable such as the device’s flash memory or “the cloud.” You point to the entire graph and just say “save.” When your app launches, you just say “load” and the entire object graph pops up in memory again, ready for use. That’s Core Data at work!
