Answer 1

Just change from responseJSON to responseString

Alamofire.upload(multipartFormData: { (multipartFormData) in

            multipartFormData.append((userid?.data(using: String.Encoding.utf8))!, withName: "user_id")

            multipartFormData.append((self.addUserBtnTag?.description.data(using: String.Encoding.utf8))!, withName: "slot")
}, to: urlString, method: .post, encodingCompletion: { (result) in
 switch result {
            case .success(let upload, _, _):

                upload.responseString { response in

                    print(response.result)
                    print("Response : ", response)

                    if response.result.isSuccess
                    {
                        let JSON = response.result.value as? NSDictionary

                        print("EditJSON : ", JSON!)
                    }
                }
            case .failure(let encodingError):
                print(encodingError)
            }

        })
