Streams of values over time. Tailored for Swift.

🚄 Release Roadmap

Learn about the Core Reactive Primitives in ReactiveSwift, and Basic Operators available offered by these primitives.

Module	Repository	Description
ReactiveCocoa	ReactiveCocoa/ReactiveCocoa	Extend Cocoa frameworks and Objective-C runtime APIs with ReactiveSwift bindings and extensions.
Loop	ReactiveCocoa/Loop	Composable unidirectional data flow with ReactiveSwift.
ReactiveSwift Composable Architecture	trading-point/reactiveswift-composable-architecture	The Pointfree Composable Architecture using ReactiveSwift instead of Combine.

ReactiveSwift offers composable, declarative and flexible primitives that are built around the grand concept of streams of values over time.

These primitives can be used to uniformly represent common Cocoa and generic programming patterns that are fundamentally an act of observation, e.g. delegate pattern, callback closures, notifications, control actions, responder chain events, futures/promises and key-value observing (KVO).

Because all of these different mechanisms can be represented in the same way, it’s easy to declaratively compose them together, with less spaghetti code and state to bridge the gap.

ReactiveSwift supports macOS 10.13+, iOS 11.0+, watchOS 4.0+, tvOS 11.0+ and Linux.

If you use Carthage to manage your dependencies, simply add ReactiveSwift to your Cartfile:

github "ReactiveCocoa/ReactiveSwift" ~> 6.1

If you use Carthage to build your dependencies, make sure you have added ReactiveSwift.framework to the "Linked Frameworks and Libraries" section of your target, and have included them in your Carthage framework copying build phase.

If you use CocoaPods to manage your dependencies, simply add ReactiveSwift to your Podfile:

pod 'ReactiveSwift', '~> 6.1'

If you use Swift Package Manager, simply add ReactiveSwift as a dependency of your package in Package.swift:

.package(url: "https://github.com/ReactiveCocoa/ReactiveSwift.git", from: "6.1.0")

1. Add the ReactiveSwift repository as a submodule of your application’s repository.
2. Run git submodule update --init --recursive from within the ReactiveCocoa folder.
3. Drag and drop ReactiveSwift.xcodeproj into your application’s Xcode project or workspace.
4. On the “General” tab of your application target’s settings, add ReactiveSwift.framework to the “Embedded Binaries” section.
5. If your application target does not contain Swift code at all, you should also set the EMBEDDED_CONTENT_CONTAINS_SWIFT build setting to “Yes”.

We also provide a Playground, so you can get used to ReactiveCocoa's operators. In order to start using it:

1. Clone the ReactiveSwift repository.
2. Retrieve the project dependencies using one of the following terminal commands from the ReactiveSwift project root directory:
   • git submodule update --init --recursive OR, if you have Carthage installed
   • carthage checkout
3. Open ReactiveSwift.xcworkspace
4. Build ReactiveSwift-macOS scheme
5. Finally open the ReactiveSwift.playground
6. Choose View > Show Debug Area

If you need any help, please visit our GitHub issues or Stack Overflow. Feel free to file an issue if you do not manage to find any solution from the archives.

Current Stable Release:

ReactiveSwift has no plan to declare ABI and module stability at the moment. It will continue to be offered as a source only dependency for the foreseeable future.
