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.

Set up RxSwift and Convert a Basic Login App to its RxSwift Counterpart

In this chapter, we will start writing code to work with the concepts we have touched on in previous chapters. We will start with environment setup and then start working towards a very basic application. While we do so, we will revisit some important concepts that we discussed earlier, while expressing the functionality in code.

The main topics covered in this chapter are as follows:

  • Setting up an RxSwift environment
  • CocoaPods and Carthage
  • Writing a singe view login app in RxSwift
