The goal of this book is to teach the skills necessary to build iOS 13 applications using SwiftUI, Xcode 11 and the Swift 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.
The book also includes in depth chapters introducing the Swift 5 programming language including data types, control flow, functions, object-oriented programming, property wrappers and error handling.
An introduction to the key concepts of SwiftUI and project architecture is followed by a guided tour of Xcode in SwiftUI development mode. The book also covers the creation of custom SwiftUI views and explains how these views are combined to create user interface layouts including the use of stacks, frames and forms.
Other topics covered include data handling using state properties and both observable and environment objects, as are key user interface design concepts such as modifiers, lists, tabbed views, context menus and user interface navigation.
The book also includes chapters covering graphics drawing, user interface animation, view transitions and gesture handling.
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 13 using SwiftUI. Assuming you are ready to download the iOS 13 SDK and Xcode 11 and have an Intel-based Mac you are ready to get started.
This book has been designed to address the needs of both existing Swift programmers and those who are new to both Swift and iOS app development. If you are familiar with the Swift 5.1 programming language, you can probably skip the Swift specific chapters. If you are not yet familiar with the new language features of Swift 5.1, however, we recommend that you at least read the sections covering implicit returns from single expressions, opaque return types and property wrappers. These features are central to the implementation and understanding of SwiftUI. If you are new to programming in Swift (or programming in general) then the entire book is appropriate for you. Just start at the beginning and keep going.
