Animating SwiftUI Applications

By: Stephen DeStefano

Overview of this book

Swift and SwiftUI are the backbone of Apple application development, making them a crucial skill set to learn. Animating SwiftUI Applications focuses on the creation of stunning animations, making you proficient in this declarative language and employing a minimal code approach. In this book, you'll start by exploring the fundamentals of SwiftUI and animation, before jumping into various projects that will cement these skills in practice. You will explore some simple projects, like animating circles, creating color spectrums with hueRotation, animating individual parts of an image, as well as combining multiple views together to produce dynamic creations. The book will then transition into more advanced animation projects that employ the GeometryReader, which helps align your animations across different devices, as well as creating word and color games. Finally, you will learn how to integrate the SpriteKit framework into our SwiftUI code to create scenes with wind, fire, rain, and or snow scene, along with adding physics, gravity, collisions, and particle emitters to your animations. By the end of this book, you’ll have created a number of different animation projects, and will have gained a deep understanding of SwiftUI that can be used for your own creations.

Exploring the Xcode interface

In this section, we will take a tour of the Xcode interface. I’m assuming that you have used Xcode before, practicing your Swift skills, which means you have a good handle on many of the things here in the interface. However, there are a few new additions to accommodate SwiftUI.

When you first start up Xcode, you see the welcome screen. On the right is a list of recent projects, and on the left, there are buttons to start a new project, open an existing project, or clone one saved in a repository.

Figure 1.1: Xcode welcome screen

We will be using the first option, which is Create a new Xcode project, for all of our projects, so select that.

The next screen lets us choose options for the project:

Let’s look at these options:

  • Product Name: This will be the name of the project. You should select a name that is directly related to what the project will...
