About the Book

This book will teach you about ReactiveSwift & ReactiveCocoa - frameworks that bring functional reactive programming to Cocoa and Cocoa Touch worlds. And, with Swift becoming open-source - to the Linux world too!

Learn about main concepts of the frameworks, how and when to use signals, signal producers, actions or properties. How to create your own signal operators and how to bring non-reactive objects into FRP world!

Eimantas Vaičiūnas

Eimantas Vaičiūnas has been using ReactiveCocoa since its early 2.x days. It has helped him immensely in refactoring legacy code-bases dependent on global state, mutating objects in multiple threads and other anti-patterns by giving clean and clear structure for the application and its data flow.
