CombineX

Open-source implementation of Apple’s Combine for processing values over time.

Though CombineX have implemented all the Combine interface, the project is still in early development.

What is Combine

Customize handling of asynchronous events by combining event-processing operators. – Apple

Combine is a Functional Reactive Programming (FRP) framework launched by Apple at WWDC 2019. It will definitely be the cornerstone of Swift programming in the foreseeable future.

Get Started

If you develop a library, it’s recommended to use CXShim so your library is compatible with SwiftUI.

Requirements

Swift 5.0+ (Xcode 10.2+)

Installation

Swift Package Manager (Recommended)

package.dependencies += [
    .package(url: "https://github.com/cx-org/CombineX", from: "0.4.0"),
]

CocoaPods

pod 'CombineX', "~> 0.4.0"

# or, if you want to use `Foundation` extensions: 
pod 'CombineX/CXFoundation', "~> 0.4.0"

Carthage

github "cx-org/CombineX" ~> 0.4.0

These libraries bring additional functionality to Combine. They are all Combine Compatible Package and you’re free to switch underlying Combine implementation between CombineX and Apple’s Combine.

CXTest: test infrastructure for Combine. It provides useful test utilities like TracingSubscriber and VirtualTimeScheduler.
CXExtensions: provides a collection of useful extensions for Combine, such as IgnoreError, DelayedAutoCancellable, etc.
CXCocoa: provides Combine extensions to Cocoa, such as KVO+Publisher, Method Interception, UIBinding, Delegate Proxy, etc.
