Reactive Programming with Swift 4 (ePub)

Learn how to solve blocking user experience and build event based reactive applications with Swift.

Key Features

• Build fast and scalable apps with RxSwift


• Apply reactive programming to solve complex problems and build efficient programs with reactive user interfaces


• Take expressiveness, scalability, and maintainability of your Swift code to the next level with this practical guide

Book Description

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.

What you will learn

• -Understand the practical benefits of Rx on a mobile platform


• -Explore the building blocks of Rx, and Rx data flows with marble diagrams


• - Learn how to convert an existing code base into RxSwift code base


• -Learn how to debug and test your Rx Code


• - Work with Playgrounds to transform sequences by filtering them using map, flatmap and other operators


• - Learn how to combine different operators to work with Events in a more controlled manner.


• - Discover RxCocoa and convert your simple UI elements to Reactive components


• - Build a complete RxSwift app using MVVM as design pattern

Who this book is for

This book is for the developers who are familiar with Swift and iOS application development and are looking out to reduce the complexity of their apps. Prior experience of reactive programming is not necessary.
