alamofire upload images with json parameters

Question

I am new to swift I want to upload images (from 1 to 4 - depending on user) and a video file(if user prefer) to my server and also send other parameters when uploading (like text and etc.) in android I was using retrofit which allowed me to use @partmap for uploading my nested Json objects. now in iOS I am using Alamofire but I couldn't find this functionality to send json with multipart how can I should do this? I don't want base 64 image I already tried this and my text content are nested clearly I want to send json parameters when uploading data for example:

image 1 = image
post->content = "some text"

@SaqibOmer my parameters are nested so i don't know how to use mentioned solution. can you help? — Mkhakpaki, Apr 22 '17 at 11:54
First of all you need to do a multipart request. You can add parameters in your request. You can create nested parameters using a NSDictionary. Also if you can edit your question add some code, may be I can answer it. — Saqib Omer, Apr 22 '17 at 12:00
@SaqibOmer i am using Alamofire as networking library and it provides upload method for uploading multipart data but in this method i can only send text data as key-value pairs but my data are nested and server side separates this data — Mkhakpaki, Apr 22 '17 at 12:02

As I mentiontioned in comments you need a multipart request.

// Image file which you want to upload.
guard let image = UIImage(named: "YourImage") else { return }


                let imgRep : NSBitmapImageRep = image.representations.first as! NSBitmapImageRep

                let imgData : Data = imgRep.representation(using: .PNG, properties: [:])!


                let cameraFileName    = "some_random_name_img.png"

                let fileUrl = URL(fileURLWithPath: cameraFileName, isDirectory: true)
                do {

                    try imgData.write(to: fileUrl, options: NSData.WritingOptions.atomic)

                    DispatchQueue.main.async {
                        // Stop Camera Session if you are capturing image from camera
                        self.cameraSession.stopRunning()

                        let someParam   = ""
                        let someParam2  = ""


                        let date = Date()
                        let dateString = "\(date)"



                        Alamofire.upload(multipartFormData: { (multipartFormData) in

                        // Add parameters in request 

         multipartFormData.append(cameraFileName.data(using: .utf8)!, withName: "name")

         multipartFormData.append(dateString.data(using: .utf8)!, withName: "startDatetime")

         multipartFormData.append(someParam.data(using: .utf8)!, withName: "userId")

         multipartFormData.append(someParam2.data(using: .utf8)!, withName: "phoneServiceId")

         multipartFormData.append(fileUrl, withName: "file")

                        }, to:"Your_Api_Url.com") // POST Url
                        { (result) in
                            switch result {
                            case .success(let upload, _ , _):

                                upload.uploadProgress(closure: { (progress) in

                                    print("uploding")
                                })

                                upload.responseJSON { response in
                                    print(response)
                                    print("done")






                                }

                            case .failure(let encodingError):
                                print("failed")
                                print(encodingError)

                            }
                        }

                    }

                }
                catch let error as NSError {
                    print("Ooops! Something went wrong: \(error)")
                }

i converted my json to string then added it as multi part data to alamofire request and it worked well thanks for your attention — Mkhakpaki, Apr 22 '17 at 12:50
