RxEnumKit is the reactive extension of EnumKit. It extends ObservableType and SharedSequenceConvertibleType to add flexibility while working with stream of enum cases.

With RxEnumKit you'll be able to extract associated values from each CaseAccessible enum element of the stream, map, compactMap, flatMap, filter and exclude cases.

Having a CaseAccessible enum, and an Observable

enum MyEvent: CaseAccessible {
    case eventA(String)
    case eventB(foo: Int)
}

let observable: Observable<MyEvent>

With RxEnumKit the following patterns will be possible:

observable.capture(case: MyEvent.eventA)
    .subscribe(onNext: { value in //String
        ...
    })

observable.map(case: MyEvent.eventB, String.init)
    .subscribe(onNext: { value in // String
        ...
    })

Requirements

Installation

RxEnumKit offers cocoapods and swiftPM

Via Cocoapods

# Podfile
use_frameworks!

target 'YOUR_TARGET_NAME' do
    pod 'RxEnumKit', '~> 1.0.2'
end

Replace YOUR_TARGET_NAME and then, in the Podfile directory, type:

$ pod install

via Swift Package Manager

Create a Package.swift file.

// swift-tools-version:5.0

import PackageDescription

let package = Package(
  name: "YourProjectName",
  dependencies: [
    .package(url: "https://github.com/gringoireDM/RxEnumKit.git", from: "1.0.2")
  ],
  targets: [
    .target(name: "YourProjectName", dependencies: ["RxEnumKit"])
  ]
)

$ swift build
