SwiftUI Cookbook - Second Edition

By: Giordano Scalzo, Edgar Nzokwe

Overview of this book

SwiftUI provides an innovative and simple way to build beautiful user interfaces (UIs) for all Apple platforms, from iOS and macOS through to watchOS and tvOS, using the Swift programming language. In this recipe-based cookbook, you’ll cover the foundations of SwiftUI as well as the new SwiftUI 3 features introduced in iOS 15 and explore a range of essential techniques and concepts that will help you through the development process. The cookbook begins by explaining how to use basic SwiftUI components. Once you’ve learned the core concepts of UI development, such as Views, Controls, Lists, and ScrollViews, using practical implementations in Swift, you'll advance to adding useful features to SwiftUI using drawings, built-in shapes, animations, and transitions. You’ll understand how to integrate SwiftUI with exciting new components in the Apple development ecosystem, such as Combine for managing events and Core Data for managing app data. Finally, you’ll write iOS, macOS, and watchOS apps by sharing the same SwiftUI codebase. By the end of this SwiftUI book, you'll have discovered a range of simple, direct solutions to common problems encountered when building SwiftUI apps.

Chapter 2: Going Beyond the Single Component with Lists and Scroll Views

In this chapter, we'll learn how to display lists in SwiftUI. List views are like UITableViews in UIKit but are significantly simpler to use. For example, no storyboards or prototype cells are required, and we do not need to remember how many rows or columns we created. Furthermore, SwiftUI's lists are modular so that you can build more significant apps from smaller components.

This chapter will also discuss new and exciting features introduced in WWDC 2021, such as lists with editable text and searchable lists. By the end of this chapter, you will understand how to display lists of static or dynamic items, add or remove items from lists, edit lists, add sections to List views, and much more.

In this chapter, we'll be covering the following recipes:

  • Using scroll views
  • Creating a list of static items
  • Using custom rows in a list
  • Adding rows to a list
  • Deleting rows from a list
  • Creating an editable List view
  • Moving the rows in a List view
  • Adding sections to a list
  • Creating editable Collections
  • Creating Searchable lists
