Rx is a [generic abstraction of computation](https://youtu.be/looJcaeboBY) expressed through `Observable<Element>` interface, which lets you broadcast and subscribe to values and other events from an `Observable` stream.

RxSwift is the Swift-specific implementation of the [Reactive Extensions](http://reactivex.io) standard.

While this version aims to stay true to the original spirit and naming conventions of Rx, this project also aims to provide a true Swift-first API for Rx APIs.

Cross platform documentation can be found on [ReactiveX.io](http://reactivex.io/).

Like other Rx implementations, RxSwift's intention is to enable easy composition of asynchronous operations and streams of data in the form of `Observable` objects and a suite of methods to transform and compose these pieces of asynchronous work.

KVO observation, async operations, UI Events and other streams of data are all unified under [abstraction of sequence](Documentation/GettingStarted.md#observables-aka-sequences). This is the reason why Rx is so simple, elegant and powerful.
