Build Status Code Coverage for RxCombine on codecov
RxCombine supports CocoaPods RxCombine supports Swift Package Manager (SPM) RxCombine supports Carthage

RxCombine provides bi-directional type bridging between RxSwift and Apple's Combine framework.

Note: This is highly experimental, and basically just a quickly-put-together PoC. I gladly accept PRs, ideas, opinions, or improvements. Thank you ! :)

Check out the Example App in the ExampleApp folder. Run pod install before opening the project.

Add the following line to your Podfile:

pod 'RxCombine'

Add the following dependency to your Package.swift file:

.package(url: "https://github.com/CombineCommunity/RxCombine.git", from: "1.6.0")

Carthage support is offered as a prebuilt binary.

Add the following to your Cartfile:

github "CombineCommunity/RxCombine"

RxCombine provides several helpers and conversions to help you bridge your existing RxSwift types to Combine.

Note: If you want to learn more about the parallel operators in Combine from RxSwift, check out my RxSwift to Combine Cheat Sheet (or on GitHub).

• Observable (and other ObservableConvertibleTypes) have a publisher property which returns a AnyPublisher<Element, Swift.Error> mirroring the underlying Observable.

let observable = Observable.just("Hello, Combine!")
observable
 .publisher // AnyPublisher<String, Swift.Error>
 .sink(receiveValue: { value in ... })

• Relays and Subjects can be converted to their Combine-counterparts using the toCombine() method, so you can use them as if they are regular Combine Subjects, and have them connected to your existing subjects.

let relay = BehaviorRelay<Int>(value: 0)
// Use `sink` on RxSwift relay
let combineSubject = relay.toCombine()
combineSubject.sink(receiveValue: { value in ... })
// Use `send(value:)` on RxSwift relay
combineSubject.send(1)
combineSubject.send(2)
combineSubject.send(3)

RxCombine provides several helpers and conversions to help you bridge Combine code and types into your existing RxSwift codebase.

• Publishers have a asObservable() method, providing an Observable<Output> mirroring the underlying Publisher.

// A publisher publishing numbers from 0 to 100.
let publisher = AnyPublisher<Int, Swift.Error> { subscriber in
 (0...100).forEach { _ = subscriber.receive(0ドル) }
 subscriber.receive(completion: .finished)
}
publisher
 .asObservable() // Observable<Int>
 .subscribe(onNext: { num in ... })

• PassthroughSubject and CurrentValueSubject both have a asAnyObserver() method which returns a AnyObserver<Output>. Binding to it from your RxSwift code pushes the events to the underlying Combine Subject.

// Combine Subject
let subject = PassthroughSubject<Int, Swift.Error>()
// A publisher publishing numbers from 0 to 100.
let publisher = AnyPublisher<Int, Swift.Error> { subscriber in
 (0...100).forEach { _ = subscriber.receive(0ドル) }
 subscriber.receive(completion: .finished)
}
// Convert a Publisher to an Observable and bind it
// back to a Combine Subject 🤯🤯🤯
publisher.asObservable()
 .bind(to: subject)
Observable.of(10, 5, 7, 4, 1, 6)
 .subscribe(subject.asAnyObserver())
