The goal of this book is to teach the skills necessary to build iOS 15 applications using SwiftUI, Xcode 13, and the Swift 5.5 programming language.
Beginning with the basics, this book provides an outline of the steps necessary to set up an iOS development environment together with an introduction to the use of Swift Playgrounds to learn and experiment with Swift.

An introduction to the key concepts of SwiftUI and project architecture is followed by a guided tour of Xcode in SwiftUI development mode.

Chapters are also provided explaining how to integrate SwiftUI views into existing UIKit-based projects and explains the integration of UIKit code into SwiftUI.
Finally, the book explains how to package up a completed app and upload it to the App Store for publication.
Along the way, the topics covered in the book are put into practice through detailed tutorials, the source code for which is also available for download.
The aim of this book, therefore, is to teach you the skills necessary to build your own apps for iOS 15 using SwiftUI. Assuming you are ready to download the iOS 15 SDK and Xcode 13 and have an Apple Mac system you are ready to get started.
