Overview of this book

If you're looking to work and experiment with powerful iOS 14 features such as widgets and App Clips to create your own apps, this iOS programming guide is for you. The book offers a comprehensive introduction for experienced programmers who are new to iOS, taking you through the entire process of learning the Swift language, writing your own apps, and publishing them on the App Store. Fully updated to cover the new iOS 14 features, along with Xcode 12 and Swift 5.3, this fifth edition of iOS 14 Programming for Beginners starts with an introduction to the Swift programming language and shows you 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 storyboards feature in the latest version of Xcode and implement the code for views, view controllers, data managers, and other aspects of mobile apps. The book will also help you apply iOS 14 features to existing apps and introduce you to SwiftUI, a new way to build apps for all Apple devices. Finally, you’ll set up testers for your app and understand what you need to do to publish your app on the App Store. By the end of this book, you'll not only be well versed in writing and publishing applications, but you’ll also be able to apply your iOS development skills to enhance existing apps.

Introducing app clips

An app clip offers a subset of your app's functionality when it's needed. It may be triggered in multiple ways, such as by visiting a website, scanning a QR Code, or tapping an NFC tag. When triggered, an information card for the app clip appears, and tapping it launches the app clip itself. You can then use the app clip to accomplish a task, and you can choose to download the full app. An app clip and the associated app are mutually exclusive. Once you have installed the app, the app clip for that app will be removed from your device.
