Questions tagged [rx-swift]

RxSwift's intention is to enable easy composition of asynchronous operations and event/data streams. Use this tag only for questions that are specific to the RxSwift - Reactive Programming paradigm, or those that require code in the language. Use the related tags [ios], [osx], [apple-watch], [cocoa-touch], and [cocoa] for (language-agnostic) questions about the platforms or frameworks.

About Rx and RxSwift

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

RxSwift 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/macOS 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.
