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 a Footer View to display more information

The Footer view that we will add will contain two pieces of information – first, how many words the user has found so far, and second, what their letter average is for each found word.

To do this, create a new SwiftUI View file and call it FooterView. This will contain the Text views we need to display that information.

Now let’s get to work and add some code. Add the following properties inside the FooterView struct:

struct FooterView: View {
    //MARK: - PROPERTIES
    @ObservedObject var appData = DataModel()
    @Binding var userEnteredWordsArray: [String]
    
    var foundWords: Double {
        let wordCount = userEnteredWordsArray.count
        //if theres no words in the array, return 0
      ...
