RxAlamofire is a RxSwift wrapper around the elegant HTTP networking in Swift Alamofire.

Wrapping RxSwift around Alamofire makes working with network requests a smoother and nicer task. Alamofire is a very powerful framework and RxSwift add the ability to compose responses in a simple and effective way.
A basic usage is (considering a simple currency converter):
let formatter = NSNumberFormatter() formatter.numberStyle = .currencyStyle formatter.currencyCode = "USD" if let fromValue = NSNumberFormatter().numberFromString(self.fromTextField.text!) { RxAlamofire.requestJSON(.get, sourceStringURL) .debug() .subscribe(onNext: { [weak self] (r, json) in if let dict = json as? [String: AnyObject] { let valDict = dict["rates"] as! Dictionary<String, AnyObject> if let conversionRate = valDict["USD"] as? Float { self?.toTextField.text = formatter .string(from: NSNumber(value: conversionRate * fromValue)) } } }, onError: { [weak self] (error) in self?.displayError(error as NSError) }) .disposed(by: disposeBag) } else { self.toTextField.text = "Invalid Input!" }
Currently, the library features the following extensions:
let stringURL = "" // MARK: URLSession simple and fast let session = URLSession.shared() _ = session.rx .response(.get, stringURL) .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } _ = session.rx .json(.get, stringURL) .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } _ = session.rx .data(.get, stringURL) .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // MARK: With Alamofire engine _ = json(.get, stringURL) .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // validation _ = request(.get, stringURL) .validate(statusCode: 200..<300) .validate(contentType: ["application/json"]) .responseJSON() .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // progress _ = request(.get, stringURL) .progress() .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // just fire upload and display progress _ = upload(Data(), urlRequest: try! RxAlamofire.urlRequest(.get, stringURL)) .progress() .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // progress and final result // uploading files with progress showing is processing intensive operation anyway, so // this doesn't add much overhead _ = request(.get, stringURL) .flatMap { request -> Observable<(Data?, RxProgress)> in let dataPart = request.rx .data() .map { d -> Data? in d } .startWith(nil as Data?) let progressPart = request.rx.progress() return Observable.combineLatest(dataPart, progressPart) { (0ドル, 1ドル) } } .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // MARK: Alamofire Session // same methods with any Alamofire Session let session = Session.default // simple case _ = session.rx.json(.get, stringURL) .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // URLHTTPResponse + JSON _ = session.rx.responseJSON(.get, stringURL) .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // URLHTTPResponse + String _ = session.rx.responseString(.get, stringURL) .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // URLHTTPResponse + Validation + JSON _ = session.rx.request(.get, stringURL) .validate(statusCode: 200 ..< 300) .validate(contentType: ["text/json"]) .json() .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // URLHTTPResponse + Validation + URLHTTPResponse + JSON _ = session.rx.request(.get, stringURL) .validate(statusCode: 200 ..< 300) .validate(contentType: ["text/json"]) .responseJSON() .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // URLHTTPResponse + Validation + URLHTTPResponse + String + Progress _ = session.rx.request(.get, stringURL) .validate(statusCode: 200 ..< 300) .validate(contentType: ["text/something"]) .flatMap { request -> Observable<(String?, RxProgress)> in let stringPart = request.rx .string() .map { d -> String? in d } .startWith(nil as String?) let progressPart = request.rx.progress() return Observable.combineLatest(stringPart, progressPart) { (0ドル, 1ドル) } } .observeOn(MainScheduler.instance) .subscribe { print(0ドル) } // Interceptor + URLHTTPResponse + Validation + JSON let adapter = // Some RequestAdapter let retrier = // Some RequestRetrier let interceptor = Interceptor(adapter: adapter, retrier: retrier) _ = session.rx.request(.get, stringURL) .validate() .validate(contentType: ["text/json"]) .responseJSON() .observeOn(MainScheduler.instance) .subscribe { print(0ドル) }
There are three ways to install RxAlamofire
Just add to your project's Podfile:
pod 'RxAlamofire'
Add following to Cartfile:
github "RxSwiftCommunity/RxAlamofire" ~> 6.1
Create a Package.swift file
// swift-tools-version:5.0
import PackageDescription
let package = Package(
name: "TestRxAlamofire",
dependencies: [
.package(url: "https://github.com/RxSwiftCommunity/RxAlamofire.git",
from: "6.1.0"),
],
targets: [
.target(
name: "TestRxAlamofire",
dependencies: ["RxAlamofire"])
]
)
To manual install this extension you should get the RxAlamofire/Source/RxAlamofire.swift imported into your project, alongside RxSwift and Alamofire.
RxAlamofire requires Swift 5.1 and dedicated versions of Alamofire (5.4.1) and RxSwift (6.0.0).
For the last RxSwift 5.1 support, please use RxAlamofire 5.7.1.
For the last Swift 5.0 support, please use RxAlamofire 5.1.0.
For the last Swift 4.2 support, please use RxAlamofire 4.5.0.
