What's in the book

Swift Design Patterns will teach you how to write cleaner, more maintainable apps. Drawing examples from SwiftUI, Cocoa, Cocoa Touch, and other key Apple frameworks, you'll learn how to design elegant apps that are easier to read, easier to scale, and easier to test.

The book includes over 20 of the most important design patterns for Swift developers, including:

  • The model-view-controller pattern that lies at the heart of Apple's class UIKit and AppKit frameworks, plus MVVM as a viable alternative.
  • A detailed discussion of what makes SwiftUI special, including hands-on tips for making SwiftUI apps more scalable and more testable.
  • Extensions, protocols, and protocol extensions that let you architect your code horizontally.
  • Notifications, selectors, and the target/action pattern to control code without increasing coupling.
  • Observers, accessors, keypaths, and delegation so you can monitor values and respond when they change.
  • Archiving data using the Codable protocol.
  • Singletons for working with shared resources.
  • Concurrency for making the most of modern Apple devices.
  • And more!

If want to improve the way you architect your Swift apps, this is the book for you.
