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.

In this chapter, we dived into the fundamentals of software development in general and explored some of the most widely used design patterns in iOS development. We explored MVC in more detail than others, since it is used in almost all iOS projects and forms the foundation of a majority of applications. In the previous chapters, we used these design patterns multiple times but many a times, we just use things without knowing the underlying concept. This chapter gave you an insight to identify exciting design patterns in the existing code base and to allow you to think in the capacity where you can understand the problem at hand and choose between the design patterns that we discussed in this chapter and beyond. Design patterns is a vast subject in itself, and this chapter provided you with a mere introduction to the concept. We highly encourage you to take some time out...
