SwiftUI Cookbook

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.

Building a bar chart

Using simple shapes, it is possible to build some nice features. For example, by just using a bunch of rectangles, we can create a bar chart.

In this recipe, we are going to create a bar chart that presents the average monthly precipitation for three European cities: Dublin, Milan, and London. The data that we'll use can be found at https://www.climatestotravel.com/.

Getting ready

This recipe doesn't need any external resources, so it's enough to create a SwiftUI project called BarChart.

How to do it…

Based on information from https://www.climatestotravel.com/, the data we have represents the average quantity of rain in centimeters. Looking at the data, we can see that the maximum rainfall is 1 centimeter, so we can adapt the bars to have a full shape for that value.

To implement our bar chart, follow these steps:

  1. Add enum to represent the months and a value type datapoint to hold the values that will be plotted on...
