Elevate SwiftUI Skills by Building Projects

By: Frahaan Hussain

Overview of this book

Elevate SwiftUI Skills by Building Projects helps you harness the cutting-edge potential of SwiftUI and its innovative and user-friendly approach to crafting user interfaces for Apple platforms with the power of Swift. This book will enhance your UI programming skills with SwiftUI through a project-based methodology, guiding you to create four real-world projects. Starting with a quick recap of Swift and SwiftUI, you’ll gradually develop projects tailored for iPhone, iPad, macOS, and watchOS using Swift and Xcode. You’ll experience SwiftUI’s versatility in action as you build a tax calculator for iPhone and a photo gallery for the iPad, which uses a larger display to enhance the viewing experience. You’ll also create an app store for Mac and, finally, get to grips with the power of SwiftUI for smaller devices such as the Apple Watch by designing a Fitness Companion app. By the end of this book, you'll have built fully functional projects across multiple platforms and gained the expertise needed to excel as a professional SwiftUI developer.

iPhone Project – Tax Calculator Functionality

In this chapter, we will work on implementing the tax calculation and page navigation functionality in our first project, the tax calculator. In the previous chapter, we looked at the design of the calculator and broke it down into two views and all the components required. We then implemented all the components using SwiftUI. At the end of the previous chapter, we effectively only had a fancy wireframe. Now, we will implement all the functionality to provide navigation between the two views, calculating the tax breakdown and displaying the calculation.

This chapter will be split into the following sections:

  • Navigating from ContentView to ResultsView
  • Input validation
  • Calculating tax breakdown
  • Extra tasks

By the end of this chapter, you will have created a fully functional tax calculator that can be used as a foundation. I’ll provide exercises as we reach the end of the chapter to implement more...
