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.

When to Become Reactive?

In Chapter 2, FRP Fundamentals, Terminology, and Basic Building Blocks, we introduced a number of concepts and called them the basic building blocks of functional reactive programming. In Chapter 3, Set up RxSwift and Convert a Basic Login App to its RxSwift Counterpart, we worked with a sample application to get a feel of RxSwift code base, and we also brushed up on some code concepts. In this chapter, we will take a step back and dive deeper into the concepts that were introduced in Chapter 2, FRP Fundamentals, Terminology, and Basic Building Blocks, and work with code to reiterate over the concepts in a different manner. We worked with a basic RxSwift application in the previous chapter and made use of Observables, subjects, and so on to get our work done without knowing the functional details of these individual concepts. Due to that, some of you might...
