Overview of this book

iOS 13 comes with features ranging from Dark Mode and Catalyst through to SwiftUI and Sign In with Apple. If you're a beginner and are looking to experiment and work with these features to create your own apps, then this updated fourth edition gets you off to a strong start. The book offers a comprehensive introduction for programmers who are new to iOS, covering the entire process of learning the Swift language, writing your own apps, and publishing them on the App Store. This edition is updated and revised to cover the new iOS 13 features along with Xcode 11 and Swift 5. The book starts with an introduction to the Swift programming language, and how to accomplish common programming tasks with it. You'll then start building the user interface (UI) of a complete real-world app, using the latest version of Xcode, and also implement the code for views, view controllers, data managers, and other aspects of mobile apps. The book will then help you apply the latest iOS 13 features to existing apps, along with introducing you to SwiftUI, a new way to design UIs. Finally, the book will take you through setting up testers for your app, and what you need to do to publish your app on the App Store. By the end of this book, you'll be well versed with how to write and publish apps, and will be able to apply the skills you've gained to enhance your apps.

Simple Values and Types

Now that you have had a short tour of Xcode, let's look at the Swift programming language.

For more information about the latest version of the Swift language, visit https://docs.swift.org/swift-book/.

First, you'll explore Swift playgrounds, an interactive environment where you can type in Swift code and have it execute and display results immediately. You'll study how Swift stores various types of data, and how it performs operations on that data. You'll also look at some cool Swift features such as type inference and type safety, which help you to write code more concisely and avoid common errors. Finally, you'll learn how to perform common operations on data and how to print messages to the Debug area to help you troubleshoot issues.

By the end of this chapter, you should be able to write simple programs that can process letters...
