How to get MIME type from an imagepath to send to server

Question

I am new to iOS app development. I am trying to get mimetype of image from the selected image path or image extension, but i don't know how to get it, as well as when i am appending image to multipatformdata, then i am getting an error like "Instance member 'append' cannot be used on type 'MultipartFormData'; did you mean to use a value of this type instead?". If anyone helps me in sending an image to server, it would be great. Thank in advance. I have mentioned my code below and to save filepath and filename i have taken an empty strings.

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info:

        if var imgUrl = info[UIImagePickerController.InfoKey.imageURL] as? URL{
            let imgName = imgUrl.lastPathComponent
            let documentDirectory = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first
            let localPath = documentDirectory?.appending(imgName)

            var image = info[UIImagePickerController.InfoKey.originalImage] as! UIImage
            let data = image.pngData()! as NSData
            data.write(toFile: localPath!, atomically: true)
            //let imageData = NSData(contentsOfFile: localPath!)!
            var photoURL = URL.init(fileURLWithPath: localPath!)//NSURL(fileURLWithPath: localPath!)
            print(photoURL)

            filename = photoURL.lastPathComponent
            fileextension = photoURL.pathExtension  // get your file extension

            img.image = image
        }

        let APPDEL = UIApplication.shared.delegate as! AppDelegate
        APPDEL.window?.rootViewController?.dismiss(animated: true, completion: nil)

        }

//Button action to send the image and parameters to server

@IBAction func updatedetails(_ sender: Any) {

        let imageobj = img.image!
        let data = imageobj.pngData()


        let acce:String = UserDefaults.standard.string(forKey: "access")!
        print(acce)

        let headers:HTTPHeaders = ["Authorization":"Bearer \(acce)"]


       // let userData:Data = try! JSONSerialization.data(withJSONObject: postParameters)
        let ImageData = imageobj.jpegData(compressionQuality: 0.5)

        Alamofire.upload(multipartFormData: { (multiFormData) in

            MultipartFormData.append(ImageData!, withName: photoURL, fileName: filename, mimeType: "image/jpeg")
            for (key, value) in Parameters {
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: "name")
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: "password")
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: "password_confirmation")
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: "city")
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: "state")
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: "address")
            }
        }, to: Constants.Userdetailsapi,method:.post,
           headers:headers,
           encodingCompletion: { encodingResult in
            switch encodingResult {
            case .success(let upload, _, _):
                upload.responseJSON { response in
                    debugPrint(response)
                    print(response)
                }
            case .failure(let encodingError):
                print(encodingError)
            }
        })    
}
