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.

Bringing everything together in ContentView

Okay – we have accomplished a lot, including creating files for single and double gears, a worm gear, a gearshift, and a fan. Now, let’s create the final file for the motor and organize all these files together in ContentView.

We’re going to use a Swift feature called Pragma Marks; this is a special syntax that labels and delineates blocks of code with a very thin line between them and makes those labels appear in one drop-down menu for easy searching and navigation. That’s very helpful when you have very large files with hundreds or thousands of lines of code.

We will also use a SwiftUI feature called Groups; this can help us further organize all the code in the ContentView file by grouping multiple objects together, such as views, scenes, or even commands, into a single unit. We will organize much of the code into groups based on whether it is animated on the x-, y-, or z-axis.

And then we will use...
