Rx is a generic abstraction of computation 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 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.

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. 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
traits - what are Single, Completable, Maybe, Driver, and ControlProperty ... and why do they exist?
testing
tips and common errors
debugging
the math behind Rx
what are hot and cold observable sequences?

... install

Integrate RxSwift/RxCocoa with my app. Installation Guide

... hack around

with the 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.

... understand the structure

RxSwift is as compositional as the asynchronous work it drives. The core unit is RxSwift itself, while other dependencies can be added for UI Work, testing, and more.

It comprises five separate components depending on each other in the following way:

┌──────────────┐    ┌──────────────┐
│   RxCocoa    ├────▶   RxRelay    │
└───────┬──────┘    └──────┬───────┘
        │                  │        
┌───────▼──────────────────▼───────┐
│             RxSwift              │
└───────▲──────────────────▲───────┘
        │                  │        
┌───────┴──────┐    ┌──────┴───────┐
│    RxTest    │    │  RxBlocking  │
└──────────────┘    └──────────────┘

RxSwift: The core of RxSwift, providing the Rx standard as (mostly) defined by ReactiveX. It has no other dependencies.
RxCocoa: Provides Cocoa-specific capabilities for general iOS/macOS/watchOS & tvOS app development, such as Shared Sequences, Traits, and much more. It depends on both RxSwift and RxRelay.
RxRelay: Provides PublishRelay, BehaviorRelay and ReplayRelay, three simple wrappers around Subjects. It depends on RxSwift.
RxTest and RxBlocking: Provides testing capabilities for Rx-based systems. It depends on RxSwift.

Usage

Here's an example	In Action
Define search for GitHub repositories ...
let searchResults = searchBar.rx.text.orEmpty .throttle(.milliseconds(300), scheduler: MainScheduler.instance) .distinctUntilChanged() .flatMapLatest { query -> Observable<[Repository]> in if query.isEmpty { return .just([]) } return searchGitHub(query) .catchAndReturn([]) } .observe(on: MainScheduler.instance)
... then bind the results to your tableview
searchResults .bind(to: tableView.rx.items(cellIdentifier: "Cell")) { (index, repository: Repository, cell) in cell.textLabel?.text = repository.name cell.detailTextLabel?.text = repository.url } .disposed(by: disposeBag)

Requirements

Xcode 12.x
Swift 5.x

For Xcode 11 and below, use RxSwift 5.x.

Installation

RxSwift doesn't contain any external dependencies.

These are currently the supported installation options:

Manual

Open Rx.xcworkspace, choose RxExample and hit run. This method will build everything and run the sample app

CocoaPods

# Podfile
use_frameworks!

target 'YOUR_TARGET_NAME' do
    pod 'RxSwift', '6.6.0'
    pod 'RxCocoa', '6.6.0'
end

# RxTest and RxBlocking make the most sense in the context of unit/integration tests
target 'YOUR_TESTING_TARGET' do
    pod 'RxBlocking', '6.6.0'
    pod 'RxTest', '6.6.0'
end

Replace YOUR_TARGET_NAME and then, in the Podfile directory, type:

$ pod install

XCFrameworks

Each release starting with RxSwift 6 includes *.xcframework framework binaries.

Simply drag the needed framework binaries to your Frameworks, Libraries, and Embedded Content section under your target's General tab.

Note: If you're using RxCocoa, be sure to also drag RxCocoaRuntime.xcframework before importing RxCocoa.

Carthage

Add this to Cartfile

github "ReactiveX/RxSwift" "6.6.0"

$ carthage update

Carthage as a Static Library

Carthage defaults to building RxSwift as a Dynamic Library.

If you wish to build RxSwift as a Static Library using Carthage you may use the script below to manually modify the framework type before building with Carthage:

carthage update RxSwift --platform iOS --no-build
sed -i -e 's/MACH_O_TYPE = mh_dylib/MACH_O_TYPE = staticlib/g' Carthage/Checkouts/RxSwift/Rx.xcodeproj/project.pbxproj
carthage build RxSwift --platform iOS

Swift Package Manager

Note: There is a critical cross-dependency bug affecting many projects including RxSwift in Swift Package Manager. We've filed a bug (SR-12303) in early 2020 but have no answer yet. Your mileage may vary. A partial workaround can be found here.

Create a Package.swift file.

// swift-tools-version:5.0

import PackageDescription

let package = Package(
  name: "RxTestProject",
  dependencies: [
    .package(url: "https://github.com/ReactiveX/RxSwift.git", .exact("6.6.0"))
  ],
  targets: [
    .target(name: "RxTestProject", dependencies: ["RxSwift", "RxCocoa"])
  ]
)

$ swift build

To build or test a module with RxTest dependency, set TEST=1.

$ TEST=1 swift test

Manually using git submodules

Add RxSwift as a submodule

$ git submodule add git@github.com:ReactiveX/RxSwift.git

Drag Rx.xcodeproj into Project Navigator
Go to Project > Targets > Build Phases > Link Binary With Libraries, click + and select RxSwift, RxCocoa and RxRelay targets
