## 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](https://en.wikipedia.org/wiki/Futures_and_promises) and [key-value observing](https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/KeyValueObserving/KeyValueObserving.html) (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.

## Installation
ReactiveSwift supports macOS 10.13+, iOS 11.0+, watchOS 4.0+, tvOS 11.0+ and Linux.
#### Carthage
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.
#### CocoaPods
If you use [CocoaPods][] to manage your dependencies, simply add
ReactiveSwift to your `Podfile`:
```
pod 'ReactiveSwift', '~> 6.1'
```
#### Swift Package Manager
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")
```
#### Git submodule
1. Add the ReactiveSwift repository as a [submodule][] of your
application’s repository.
1. Run `git submodule update --init --recursive` from within the ReactiveCocoa folder.
1. Drag and drop `ReactiveSwift.xcodeproj` into your application’s Xcode
project or workspace.
1. On the “General” tab of your application target’s settings, add
`ReactiveSwift.framework` to the “Embedded Binaries” section.
1. If your application target does not contain Swift code at all, you should also
set the `EMBEDDED_CONTENT_CONTAINS_SWIFT` build setting to “Yes”.
## Playground
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.
1. 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`
1. Open `ReactiveSwift.xcworkspace`
1. Build `ReactiveSwift-macOS` scheme
1. Finally open the `ReactiveSwift.playground`
1. Choose `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.
