Alamorefire (Swift 3): Неоднозначная ссылка на члена 'загрузки (..'

Question

я использую Alamorefire для Swift 3 но получил ошибку:. Ambiguous reference to member 'upload Вот мой код:

Alamofire.upload(.post, url, 
     multipartFormData: { multipartFormData in 

      // import parameters 
      for i in 0 ..< params.count { 
       for (key, value) in params[i] { 
        multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key) 
       } 
      } 

      // import image to request 
      multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "file.jpg", mimeType: "image/jpeg") 
     }, // you can customise Threshold if you wish. This is the alamofire's default value 
     encodingMemoryThreshold: SessionManager.multipartFormDataEncodingMemoryThreshold, 
     encodingCompletion: { encodingResult in 
      switch encodingResult { 
      case .Success(let upload, _, _): 
       upload.responseJSON { response in 

        debugPrint(response.result) 

       } 
      case .Failure(let encodingError): 
       print(encodingError) 

      } 
    }) 

Что случилось с моим кодом?

Try ниже код

Alamofire.upload(multipartFormData: { (multipartFormData) in 
    multipartFormData.append(UIImageJPEGRepresentation(self.photoImageView.image!, 0.5)!, withName: "photo_path", fileName: "swift_file.jpeg", mimeType: "image/jpeg") 
    for (key, value) in parameters { 
     multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key) 
    } 
    }, to:"http://server1/upload_img.php") 
{ (result) in 
    switch result { 
    case .success(let upload, _, _): 

     upload.uploadProgress(closure: { (Progress) in 
      print("Upload Progress: \(Progress.fractionCompleted)") 
     }) 

     upload.responseJSON { response in 
      //self.delegate?.showSuccessAlert() 
      print(response.request) // original URL request 
      print(response.response) // URL response 
      print(response.data)  // server data 
      print(response.result) // result of response serialization 
      //      self.showSuccesAlert() 
      //self.removeImage("frame", fileExtension: "txt") 
      if let JSON = response.result.value { 
       print("JSON: \(JSON)") 
      } 
     } 

    case .failure(let encodingError): 
     //self.delegate?.showFailAlert() 
     print(encodingError) 
    } 

}
