Alamofire and RxSwift

gistfile1.m

let rx_request = Observable<Value>.create { (observer) -> Disposable in
            let requestReference = Alamofire.request(.POST, url, parameters: payload)
                .responseJSON(completionHandler: { (response) in
                    if let value = response.result.value {
                        observer.onNext(value)
                        observer.onCompleted()
                    }else if let error = response.result.error {
                        observer.onError(error)
                    }
                })
            return AnonymousDisposable {
                requestReference.cancel()
            }
        }

Smart move using the AnonymousDisposable to cancel the request 👍

How would we use this with alamofire object mapper?

AnonymousDisposable was deprecated in the latest version. I found this on the changelog:

* Deprecates AnonymousDisposable in favor of Disposables.create(with:)

Replace it with this and it will work:

return Disposables.create(with: { requestReference.cancel() })
