What is ReactiveSwift in a nutshell?
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
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
pod 'ReactiveSwift', '~> 6.1'
Swift Package Manager
If you use Swift Package Manager, simply add ReactiveSwift as a dependency
of your package in
.package(url: "https://github.com/ReactiveCocoa/ReactiveSwift.git", from: "6.1.0")
- Add the ReactiveSwift repository as a submodule of your application’s repository.
git submodule update --init --recursivefrom within the ReactiveCocoa folder.
- Drag and drop
ReactiveSwift.xcodeprojinto your application’s Xcode project or workspace.
- On the “General” tab of your application target’s settings, add
ReactiveSwift.frameworkto the “Embedded Binaries” section.
- If your application target does not contain Swift code at all, you should also
EMBEDDED_CONTENT_CONTAINS_SWIFTbuild setting to “Yes”.
We also provide a Playground, so you can get used to ReactiveCocoa's operators. In order to start using it:
- Clone the ReactiveSwift repository.
- Retrieve the project dependencies using one of the following terminal commands from the ReactiveSwift project root directory:
git submodule update --init --recursiveOR, if you have Carthage installed
- Finally open the
View > Show Debug Area

Plan of Record
ABI stability 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.
