Early Praise for Core Data in Objective-C, Third Edition

Marcus’s books have long been my go-to recommendation for people who want to learn about Core Data. With new information for beginners and experts alike, they are a great insight into how you should be using Core Data and the features that it offers.

Core Data is a very powerful resource for any developer interested in iOS and OS X application development. This book does an excellent job of explaining the details of Core Data, a topic that is otherwise considered quite hard to grasp. A must-read book for anyone developing data-intensive applications.

Marcus has a profound understanding of Core Data, and this book describes not only the basics of working with Core Data, but also how to do so in a performant manner, with explanations and examples. This is an indispensable reference, alongside Apple’s documentation, and one that will quickly make Core Data your go-to persistence mechanism. You’ll be able to deal with anything that comes up with confidence.
