Swift 3 - Alamofilre 4.0 multipart image upload with progress - ios

Question

I've done with image upload and its successfully uploaded on server using below method.
Now I want to upload image with its progress so can any one tell me how to do? I found on everywhere but didn't got the correct solution.
Code for image upload without it's progress :
#IBAction func uploadClick(_ sender: AnyObject) {
// define parameters
let parameters = [
"file_name": "swift_file.jpeg"
]
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.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)
}
}
}

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)
}
}
