Book Description

Core Data best practices by example: from simple persistency to multithreading and syncing This book strives to give you clear guidelines for how to get the most out of Core Data while avoiding the pitfalls of this flexible and powerful framework. We start with a simple example app and extend it step by step as we talk about relationships, advanced data types, concurrency, syncing, and many other topics. Later on, we go well beyond what's needed for the basic example app. We'll discuss in depth how Core Data works behind the scenes, how to get great performance, the trade-offs between different Core Data setups, and how to debug and profile your Core Data code. All code samples in this book are written in Swift. We show how you can leverage Swift's language features to write elegant and safe Core Data code. We expect that you're already familiar with Swift and iOS, but both newcomers and experienced Core Data developers will find a trove of applicable information and useful patterns.

Book Description

Today, virtually every non-trivial iPhone and iPad app must manage data—quickly, smoothly, reliably, and with minimal impact on the CPU to conserve battery life. Core Data, Apple’s ready-made data persistence layer, can help you achieve all these goals. In Core Data for iOS, two leading iOS developers teach you the entire Core Data framework from the ground up. Writing for intermediate-to-advanced iOS developers, Tim Isted and Tom Harrington thoroughly explain how Core Data is used on iOS devices, introduce each of its primary classes, and show how they interact to provide amazing functionality with minimal configuration. You’ll learn how to store, fetch, and validate data; provide it efficiently to views; and much more. Isted and Harrington first give you a firm grounding in the technology, and then present real-world examples. They present multiple sample projects, as well as a start-to-finish, chapter-length case study. Coverage includes • Understanding Core Data’s features, classes, and interactions • Using Core Data in MVC-based iOS app development • Mapping relational data to object models, and building them with Xcode 4’s Data Modeler • Working with managed objects and using UITableView to display them • Creating predicates to match numbers, data, and objects • Maintaining compatibility across versions of an app’s data model • Tracking managed object contexts across view controllers • Using Core Data’s automatic Undo functionality • Integrating abstract entities, entity inheritance, and multiple view controllers into a complete app • Optimizing for iOS devices’ tight memory limits • Diagnosing and fixing common Core Data problems Introducing Addison-Wesley’s new Core Frameworks Series, written for experienced iOS developers by world-class Mac and iOS developers, these are the first comprehensive, code-rich reference guides to Apple’s Core Frameworks.
