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.

Adding the images to the scene

There are four images we need to add to our scene, which we will add in the following order:

  • The background
  • The right leg
  • The girl
  • The left leg

So, let’s get started!

Adding the background

We’ll add the background inside a ZStack, this will be the first view in the file, and so all subsequent views will be placed on top of this. Here is the code you need:

var body: some View {
        ZStack {
            Image("tree").resizable()
                .frame(width: 550, height: 900)
               }
            }

In ZStack, we call the Image initializer and pass in the tree string. Next...
