Alamofire taking too much time to upload 6 images with some params which nearly total around 2 mb

Question

PHP side code:

Swift 3 -> Alamofire code:

func globalFuncUploadFile(withParams: [String:String], forURL: String, imageData: [String:Data], completionHandler: @escaping (JSON?, NSError?) -> ()) {
    // To create a Semaphore to Sync this asyc method
    print(forURL)
    let semaphore       =   DispatchSemaphore(value: 0)
    Alamofire.upload(multipartFormData: { (MultipartFormData) in
        print("\n\n\n\nFile is appending with URL")

        for (key,data) in imageData{
            print("\(key) is appending")
            MultipartFormData.append(data.base64EncodedData(), withName: key, fileName: key, mimeType: "\(key)/JPEG)")
        }
        for (key,value) in withParams{
            print("\(key) is appending")
            MultipartFormData.append(value.data(using: .utf8)!, withName: key)
        }
        print("of size \(MultipartFormData.contentLength)")
        }, to: forURL,
           encodingCompletion: { encodingResult in
            switch encodingResult {
            case .success(let upload, _, _):

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

                upload.responseString { (value) in
                    //Show Alert in UI
                    switch value.result {
                    case .success(let valueJson):
                    print("Data uploaded \(valueJson)")
                        completionHandler(JSON(valueJson), nil)
                        break

                    case .failure(let internalError):
                        print("Data not uploaded -> \(internalError)")
                        completionHandler(nil, internalError as NSError?)
                        break
                    }
                }
              break
            case .failure(let encodingError):
                //Show Alert in UI
                print("Data not uploaded -> \(encodingError)")
                completionHandler(nil, encodingError as NSError?)
                break
            }


            //Awaking Semaphore that session is complete
            semaphore.signal()
        }
    )
    // Waiting for the semaphore signal
    _ = semaphore.wait(timeout: .distantFuture)
}

If by any chance taking almost a minute, Images would uploaded to server by getting successful message from php code, then the images will not saved to database and generates this error:

PHP Notice:  Undefined index: image1 in address.php on line 14
PHP Notice:  Undefined index: image2 in address.php on line 15
PHP Notice:  Undefined index: image3 in address.php on line 16
PHP Notice:  Undefined index: image4 in address.php on line 17
PHP Notice:  Undefined index: image5 in address.php on line 18
PHP Notice:  Undefined index: prescription_image in address.php on line 143

But most of the times, say 99 times out of 100; The time out error is generates in swift by alamofire (Swift Error Log with uploading process):

Hmm some extra information: The whole thing is working for both WIFI and for Network when I was testing in mobile with SIM but when SIM got ejected by the owner; I left up with only WIFI, and face this thing.

There is gap of a day between SIM and no SIM scenario as I'm on leave. In between there have some changes on php side which is hard to mention by me. Thanks in advance for your cooperation.

Sad but no help in 72 hours and as there is saying "Who doesn't got help from anywhere, eventually able to help himself".

The problem is in data format. The php side guy changed the method of getting image into base64String which is previously in data format and on swift side I'm still sending image in data format. When alamofire is trying to handshake with php, php got confused by data format and takes long time to reply back.

Alamofire taking too much time to upload 6 images with some params which nearly total around 2 mb
