Overview of this book

Mastering iOS 14 development isn’t a straightforward task, but this book can help you do just that. With the help of Swift 5.3, you’ll not only learn how to program for iOS 14 but also be able to write efficient, readable, and maintainable Swift code that reflects industry best practices. This updated fourth edition of the iOS 14 book will help you to build apps and get to grips with real-world app development flow. You’ll find detailed background information and practical examples that will help you get hands-on with using iOS 14's new features. The book also contains examples that highlight the language changes in Swift 5.3. As you advance through the chapters, you'll see how to apply Dark Mode to your app, understand lists and tables, and use animations effectively. You’ll then create your code using generics, protocols, and extensions and focus on using Core Data, before progressing to perform network calls and update your storage and UI with the help of sample projects. Toward the end, you'll make your apps smarter using machine learning, streamline the flow of your code with the Combine framework, and amaze users by using Vision framework and ARKit 4.0 features. By the end of this iOS development book, you’ll be able to build apps that harness advanced techniques and make the best use of iOS 14’s features.

Summary

In this chapter, we have learned about the basics of Combine: what a publisher is, what a subscriber is, why we need operators, which ones are more useful, and how all these elements chain together to help us.

We have built two different apps to demonstrate how Combine can help in our apps, from processing user interface events, decoding, and applying business rules, to creating error-proof streams and methods to recover from operations that fail. Combine provides us with a lot of built-in functionalities that will make our code easy to read and maintain.

In the next chapter, we are going to learn about one of the new features of iOS 14: App Clips.
