Reactive Programming with Swift 4

By: Navdeep Singh

Overview of this book

RxSwift belongs to a large family of Rx implementations in different programming languages that share almost identical syntax and semantics. Reactive approach will help you to write clean, cohesive, resilient, scalable, and maintainable code with highly configurable behavior. This book will introduce you to the world of reactive programming, primarily focusing on mobile platforms. It will tell how you can benefit from using RxSwift in your projects, existing or new. Further on, the book will demonstrate the unbelievable ease of configuring asynchronous behavior and other aspects of the app that are traditionally considered to be hard to implement and maintain. It will explain what Rx is made of, and how to switch to reactive way of thinking to get the most out of it. Also, test production code using RxTest and the red/ green approach. Finally, the book will dive into real-world recipes and show you how to build a real-world app by applying the reactive paradigm. By the end of the book, you’ll be able to build a reactive swift application by leveraging all the concepts this book takes you through.

React to UI Events – Start Subscribing

So far, many of you might have noted that we have used another library, RxCocoa, in our pod files, and the library was used to make view components become reactive. In this chapter, we will dig deeper to understand RxViews and view bindings. We will start with RxCocoa traits, then understand binding UI elements with data elements, and see how to bind table views and collection views in the later half of this chapter.

We will cover the following topics in this chapter:

  • RxCocoa traits
  • Binding data elements
  • Table view bindings
  • Collection view bindings
