About Rx

Rx is a generic abstraction of computation expressed through Observable<Element> interface.

This is a Swift version of Rx.

It tries to port as many concepts from the original version as possible, but some concepts were adapted for more pleasant and performant integration with iOS/OSX environment.

Cross platform documentation can be found on ReactiveX.io.

Like the original Rx, its intention is to enable easy composition of asynchronous operations and event/data streams.

KVO observing, async operations and streams are all unified under abstraction of sequence. This is the reason why Rx is so simple, elegant and powerful.

I came here because I want to ...

... understand

• why use rx?
• the basics, getting started with RxSwift
• units - what is Driver, ControlProperty, and Variable ... and why do they exist?
• testing
• tips and common errors
• debugging
• the math behind Rx
• what are hot and cold observable sequences?
• what does the the public API look like?

... install

• Integrate RxSwift/RxCocoa with my app. Installation Guide

... hack around

• with example app. Running Example App
• with operators in playgrounds. Playgrounds

... interact

• All of this is great, but it would be nice to talk with other people using RxSwift and exchange experiences.
  Join Slack Channel
• Report a problem using the library. Open an Issue With Bug Template
• Request a new feature. Open an Issue With Feature Request Template

... compare

• with other libraries.

... find compatible

• libraries from RxSwiftCommunity.
• Pods using RxSwift.

... see the broader vision

• Does this exist for Android? RxJava
• Where is all of this going, what is the future, what about reactive architectures, how do you design entire apps this way? Cycle.js - this is javascript, but RxJS is javascript version of Rx.
