Mehrdeutiger Verweis auf Mitglied 'upload (_: _: headers: file :)'

Question

Der folgende Code funktioniert perfekt in Swift 3, um eine Bilddatei als Multipart hochzuladen. Allerdings konnte ich in Swift 2.2 nichts Ähnliches erreichen. Wenn ich versuche, dies in Swift 2.2 zu verwenden, bekomme ich die Nachricht Ambiguous reference to member 'upload(_:_:headers:file:)'

Gibt es eine Möglichkeit, das gleiche in Swift 2.2 zu erreichen? Ich habe mehrere ähnliche Fragen gefunden, haben aber nur Lösungen gefunden, die 3.

func submitFile(entryId: Int, entryDetailValue: String, fieldId: Int, fieldType: String) { 

    let parameters = [ 
     "entryId": "\(entryId)", 
     "entryDetail": entryDetailValue, 
     "fieldId": "\(fieldId)", 
     "type": fieldType 
    ] 

    print(parameters) 

    Alamofire.upload(multipartFormData: { (multipartFormData) in 
     multipartFormData.append(UIImageJPEGRepresentation(self.imageView.image!, 1)!, withName: "file", fileName: "swift_file.jpeg", mimeType: "image/jpeg") 
     for (key, value) in parameters { 
      multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key) 
     } 
     }, to:"<my endpoint url>") 
    { (result) in 
     switch result { 
     case .success(let upload, _, _): 

      upload.uploadProgress(closure: { (progress) in 
       //Print progress 
       print(progress) 
      }) 

      upload.responseData { response in 
       print(response.result) 
      } 

     case .failure(let error): 
      print(error) 
     } 
    } 

}

In swift 3 versuchen, diese

func uploadImageWithParameter() 
{ 
    let id = String(describing: userDefaults.value(forKey: USER_LOGIN_ID)!) 

    var parameters = [String:String]() 
    parameters = ["title":headingTextfield.text!, 
        "id":id, 
        "description":descriptionTextview.text, 
        "author":authorTextfield.text!, 
        "url": urlTextfield.text!] 

    Alamofire.upload(multipartFormData: { (multipartFormData) in 
     multipartFormData.append(UIImageJPEGRepresentation(self.capturedImage, 0.5)!, withName: "pic", fileName: "swift_file.jpeg", mimeType: "image/jpeg") 
     for (key, value) in parameters { 
      multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key) 
     } 

    }, to:"your url") 
    { (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) 
     } 

    } 
}
