- RxSwift 3.x / Swift 3.x can be found in rxswift-3.0 branch.
Rx is a generic abstraction of computation expressed through
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/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.
I came here because I want to ...
- why use rx?
- the basics, getting started with RxSwift
traits - what are
Variable... and why do they exist?
- tips and common errors
- the math behind Rx
- what are hot and cold observable sequences?
- Integrate RxSwift/RxCocoa with my app. Installation Guide
... hack around
- All of this is great, but it would be nice to talk with other people using RxSwift and exchange experiences.

Rx doesn't contain any external dependencies.
These are currently the supported options:
Open Rx.xcworkspace, choose
RxExample and hit run. This method will build everything and run the sample app
# Podfile use_frameworks! target 'YOUR_TARGET_NAME' do pod 'RxSwift', '~> 4.0' pod 'RxCocoa', '~> 4.0' end # RxTest and RxBlocking make the most sense in the context of unit/integration tests target 'YOUR_TESTING_TARGET' do pod 'RxBlocking', '~> 4.0' pod 'RxTest', '~> 4.0' end
YOUR_TARGET_NAME and then, in the
Podfile directory, type:
$ pod install
Add this to
github "ReactiveX/RxSwift" ~> 4.0
$ carthage update
swift build --version:
Swift 4.0.0-dev (swiftpm-13126)
// swift-tools-version:4.0 import PackageDescription let package = Package( name: "RxTestProject", dependencies: [ .package(url: "https://github.com/ReactiveX/RxSwift.git", "4.0.0" ..< "5.0.0") ], targets: [ .target(name: "RxTestProject", dependencies: ["RxSwift", "RxCocoa"]) ] )
$ swift build
To build or test a module with RxTest dependency, set
TEST=1. (RxSwift >= 3.4.2)
$ TEST=1 swift test
Manually using git submodules
- Add RxSwift as a submodule
$ git submodule add email@example.com:ReactiveX/RxSwift.git
