SwiftUI Projects

Overview of this book

Released by Apple during WWDC 2019, SwiftUI provides an innovative and exceptionally simple way to build user interfaces for all Apple platforms with the power of Swift. This practical guide involves six real-world projects built from scratch, with two projects each for iPhone, iPad, and watchOS, built using Swift programming and Xcode. Starting with the basics of SwiftUI, you’ll gradually delve into building these projects. You’ll learn the fundamental concepts of SwiftUI by working with views, layouts, and dynamic types. This SwiftUI book will also help you get hands-on with declarative programming for building apps that can run on multiple platforms. Throughout the book, you’ll work on a chart app (watchOS), NBA draft app (watchOS), financial app (iPhone), Tesla form app (iPhone), sports news app (iPad), and shoe point-of-sale system (iPad), which will enable you to understand the core elements of a SwiftUI project. By the end of the book, you’ll have built fully functional projects for multiple platforms and gained the knowledge required to become a professional SwiftUI developer.

Accessibility and fonts

In every app we work on from now on, we are going to use a custom font. The fonts we'll be using throughout this book are in each project file for you. But I wanted to go over fonts in general and how we'll use this class.

We used system fonts in the previous chapter, but I did not cover them in depth. Apple would prefer fonts that can scale, and even though we are making a watch app in this chapter, I would like to make it a habit to use scalable fonts in every app.

Let's look at how system fonts work first.

System fonts

In Storyboards, we had a panel to set your fonts manually, but in SwiftUI, it is effortless to append a font to Text ("Craig"). Let's look at a couple of examples again of system fonts:

Text("Craig Clayton").font(.headline)
Text("Craig Clayton").font(.subheadline)
Text("Craig Clayton").font(.title)
Text("Craig Clayton").font(.largeTitle)
Text("Craig Clayton...
