Learning Core Data for iOS with Swift, 2nd Edition

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

Get Started Fast with Core Data App Development Using iOS 9, Swift, and Xcode 7

Core Data is a remarkably mature, stable, and fast platform for data access, and Swift is a world-class language for applying it. Now, there’s a complete guide to using Core Data and Swift together in production apps. Tim Roadley shows you how to gain the benefits of a relational database without writing SQL queries, so you can get more done faster, with less coding.

This book fully reflects Apple’s latest iOS 9 platform innovations and teaches Core Data entirely with Swift examples. It guides you step-by-step through creating a modern data-driven iOS app that fully integrates iCloud via CloudKit for public data sharing.

Roadley introduces up-to-date patterns and best practices designed to overcome the frustrations of Core Data development. Each chapter builds on the last, introducing new topics in the order you’ll implement them and extending your skills simply and intuitively.

Each chapter offers downloadable project code, along with exercises to help you explore even further, either as a self-learner or a student in an iOS development course. Roadley even shows how to build helper classes that simplify reuse of his example code.

If you’re an experienced iOS developer, here are all the Swift skills and resources you need to integrate data into any app—quickly, easily, and painlessly.
