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.

Setting up the project and adding a Binding variable

Okay, let’s get started! As always, we’ll create a new Xcode project (I’m going to call mine Elevator).

Next, in the GitHub repo, take all the images from the Chapter 11 folder and drop them into the Asset Catalog. These images include doorDrame, leftDoor, rightDoor, inside, man, man2, man3, and man4.

Then, drop the audio files – doorsOpenClose and elevatorChime – into the Project Navigator.

Next, we’re going to need a new file where we can assemble the elevator and add the people, so create a new SwiftUI View file and call it ElevatorAndPeopleView. We only need one variable in this file, which will be the Binding variable. Let’s add it at the top, inside the ElevatorAndPeopleView struct:

    @Binding var doorsOpened: Bool

This variable will control the elevator doors opening and closing.

Let’s update the Previews so that the code will build...
