SwiftUI Cookbook: Discover solutions and best practices to tackle the most common problems while building SwiftUI apps


Preface

SwiftUI, introduced during Apple's 2019 Worldwide Developer Conference (WWDC) 2019, provides an innovative and simple way to build user interfaces across all Apple platforms. SwiftUI code is easy to read and write because it uses Swift's declarative programming syntax.

This book covers the foundations of SwiftUI, as well as the new features of SwiftUI 2.0 introduced in iOS 14. A few recipes are addressed to make some new SwiftUI 2.0 components retrocompatible with iOS 13, such as the Map View or the Sign in with Apple View.

By the end of this book, you'll have simple, direct solutions to common problems found in building SwiftUI apps, and you'll know how to build visually compelling apps using SwiftUI 2.0 and iOS 14.

Who this book is for
This book is for mobile developers who want to learn SwiftUI as well as experienced iOS developers transitioning from UIKit to SwiftUI. The book assumes knowledge of the Swift programming language. Although knowledge of object-oriented design and data structures will be useful, it is not necessary.

What this book covers

Chapter 1, Using the Basic SwiftUI Views and Controls, explains how to implement various SwiftUI layout components, such as HStack, VStack, ZStack, LazyHStack, LazyVStack, LazyVGrid, and other layout components. It also covers how to capture various user gestures and how to use form fields. This chapter covers the basic building blocks for creating SwiftUI apps.

Chapter 2, Going Beyond the Single Component with List and Scroll Views, explains how to implement Lists, ScrollViews, and Expanding views. Learn to improve the load time of large data by using Lazy Grids and Lazy Stacks.

Chapter 3, Viewing while Building with SwiftUI Preview, explains how to unleash the power and capabilities of SwiftUI previews to speed up UI development time.

Chapter 4, Creating New Components and Grouping Views in Container Views, explains how to group views, use container views, and implement “architectural views such as NavigationView and TabView.

Chapter 5, Presenting Extra Information to the User, provides various ways of presenting extra information to the user, such as alerts, modals, context menus, and popovers.

Chapter 6, Drawing with SwiftUI, explains how to implement drawings in SwiftUI by using built-in shapes, and drawing custom paths and polygons, using UIBezierPath and CGPath.

Chapter 7, Animating with SwiftUI, explains how to implement basic animations, spring animations, and implicit and delayed animations, as well as how to combine transitions, create custom transitions, and create asymmetric transitions.

Chapter 8, Driving SwiftUI with Data, explains how to use the SwiftUI binding mechanism to populate and change views when the bounded data changes.

Chapter 9, Driving SwiftUI with Combine, explains how to integrate Combine to drive the changes of the SwiftUI views. You'll explore how to validate forms, fetch data asynchronously from the network, and test Combine-based apps.

Chapter 10, Handling Authentication and Firebase with SwiftUI, explains how to implement authentication in your app and store user information.

Chapter 11, Handling Core Data in SwiftUI, explains how to implement persistence using SwiftUI and Core Data, saving, deleting, and modifying objects in a Core Data local database.

“Chapter 12, Cross-Platform SwiftUI, explains how to create a cross-platform SwiftUI app that works on iOS, macOS, and watchOS.

Chapter 13, SwiftUI Tips and Tricks, covers several SwiftUI tips and tricks that will help you solve a number of common problems, such as testing the views, integrating a MapKit view, and using custom fonts.
