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.

Book Description

Dive into Concurrency in iOS!Concurrency is the concept of multiple things, or pieces of work, running at the same time. With the addition of CPU cores in our devices, knowing how to properly utilize your customer's hardware to the maximum is absolutely a must. Unfortunately, proper concurrency in iOS apps is one of the lesser-known, lower-level topics, that every developer wants to (and should) understand properly, but is usually intimidated by.This is where Concurrency by Tutorials comes to the rescue! In this book, you'll learn everything there is to know about how to write performant and concurrent code for your iOS apps. Who This Book Is ForThis book is for intermediate iOS developers who already know the basics of iOS and Swift development but want to enrich their knowledge, learning more about how to efficiently perform tasks without affecting the performance of their app, and how to properly divide work to utilize hardware to the fullest extent.Topics Covered in Concurrency by TutorialsWhat & Why: Learn what is Concurrency and why would you even want to utilize it in your apps?Grand Central Dispatch: Learn about Apple's implementation of C's libdispatch, also known as GCD, it's one of the simplest ways to queue up tasks to be run in parallel.Operations & Operation Queues: When GCD doesn't quite cut it, you'll learn how to further customize and reuse your concurrent work using Operations and Operation Queues.Common Concurrency Problems: Learn about some of the problems you could face while developing concurrent applications, such as Race Conditions, Deadlocks, and more.Threads & Thread Sanitizer: Understand various threading-related concepts and how these connect to the knowledge you've accumulated throughout this book. You'll also learn how to use Thread Sanitizer to ease your debugging when things go wrong.This book is sure to make you a pro in building concurrent and performant applications, and finally understanding how these lower-level APIs work to the fullest, pushing your app to the top!
