Alamofire 4.0 ambiguous reference on upload

I am trying to upload using alamofire, I am using the following code:

Alamofire.upload(urlRequest.0, to: urlRequest.1, method: .put)
            .uploadProgress(queue: DispatchQueue.utility) { progress in
                print("Upload Progress: \(progress.fractionCompleted)")
            }

            .responseJSON { response in
            //Some code here

        }

Where urlRequest is a tuple: (URLConvertible, Data). I am getting the compiler error : "Ambiguous reference to member 'upload(_:to:method:headers:)'". Any ideas what I am doing wrong here? Any pointers would be really appreciated! Thanks!

Solution

  • You may need to add the headers parameter:

    Alamofire.upload(urlRequest.0, to: urlRequest.1, method: .put, headers: nil)
.uploadProgress { progress in 
        print("Upload Progress: \(progress.fractionCompleted)")  
}

    while a tuple's types should stand in this order: (Data, URLConvertible)
