Swift 3 - Alamofilre 4.0 multipart image upload with progress

Finally got the solution after search a lot. We just need to put uploadProgress block within result block.

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)        }    }
