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.

Displaying a character count next to each word in the list

I also want to add a number next to each word that indicates how many letters are in the word that the user has entered. Later, we will take this number from each word and add them together to get an average of how the user is doing in terms of the length of words they are entering.

We can put this number inside a circle, and luckily this is very easy, as Swift gives us system images of circles with numbers in them that are already created; all we have to do is call them up. So, back in ContentView, then inside the List view, let’s put the Text view inside of an HStack (so they are side by side), and add an Image view for the number circle:

List(guessedWordsArray, id: \.self) { word in
        HStack {
            Image(systemName:
