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.

Exploring more views and controls (iOS 14+)

In this section, we introduce some views and controls that did not clearly fit in any of the earlier created recipes. We'll look at the ProgressView, ColorPicker, Link, and Menu views.

ProgressView are used to show the degree of completion of a task. There are two types of ProgressView: indeterminate progress views show a spinning circle till a task is completed, while determinate progress views show a bar that gets filled up to show the degree of completion of a task.

ColorPicker views allow users to select from a wide range of colors, while Menu views present a list of items that users can choose from to perform a specific action.

Getting ready

Let's start by creating a new SwiftUI project called MoreViewsAndControls.

How to do it…

Let's implement some views and controls in the ContentView.swift file. We will implement each item in a separate Section within a List. The steps are given here:
