    ]

    let boundary = generateBoundaryString()

    request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")


    let imageData = UIImageJPEGRepresentation((imageView?.image!)!, 1)

    if(imageData==nil)  { return; }

    request.httpBody = createBodyWithParameters(parameters: param, filePathKey: "file", imageDataKey: imageData! as NSData, boundary: boundary) as Data

    myActivityIndicator.isHidden = false
    myActivityIndicator.startAnimating();

    let task = URLSession.shared.dataTask(with: request as URLRequest)
    {
        data, response, error in

        if error != nil
        {
            print("******** error=\(error)")
            return
        }

        // You can print out response object
        print("\n\n******* response *******\n\n")

    task.resume()
}


func createBodyWithParameters(parameters: [String: String]?, filePathKey: String?, imageDataKey: NSData, boundary: String) -> NSData {

    return body

Please give a try with below code to upload the image on your server, also replace fileName variable value with one in which you want to send the image file to your server.

func uploadImage(urlString:String,headers:[String:String]?,params:[String:String]?,image:UIImage?){
    let boundary: String = "------VohpleBoundary4QuqLuM1cE5lMwCy"
    let contentType: String = "multipart/form-data; boundary=\(boundary)"

    let request = NSMutableURLRequest()
    request.url = URL(string: urlString)
    if let tHeaders = headers {
        for (key, value) in tHeaders {
            request.setValue(value, forHTTPHeaderField: key)
        }
    }
    request.httpShouldHandleCookies = false
    request.timeoutInterval = 60
    request.httpMethod = "POST"
    request.setValue(contentType, forHTTPHeaderField: "Content-Type")

    let body = NSMutableData()
    if let parameters = params {
        for (key, value) in parameters {
            body.append("--\(boundary)\r\n".data(using: String.Encoding.utf8)!)
            body.append("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n".data(using: String.Encoding.utf8)!)
            body.append("\(value)\r\n".data(using: String.Encoding.utf8)!)
        }
    }
    //which field you have to sent image on server
    let fileName: String = "file"
    if image != nil {
        body.append("--\(boundary)\r\n".data(using: String.Encoding.utf8)!)
        body.append("Content-Disposition: form-data; name=\"\(fileName)\"; filename=\"image.png\"\r\n".data(using: String.Encoding.utf8)!)
        body.append("Content-Type:image/png\r\n\r\n".data(using: String.Encoding.utf8)!)
        body.append(UIImagePNGRepresentation(image!)!)
        body.append("\r\n".data(using: String.Encoding.utf8)!)
    }
    body.append("--\(boundary)--\r\n".data(using: String.Encoding.utf8)!)
    request.httpBody = body as Data
    let session = URLSession.shared
    let task = session.dataTask(with: request as URLRequest) { (data, response, error) in
        if(error != nil){
            print(String(data: data!, encoding: .utf8) ?? "No response from server")
        }
    }
    task.resume()
}

at your PHP server, you can get your file name like this

<?php
   echo $_FILES['file']['name'];
?>

func webServiceImageUploadForMyProfile(image:UIImage,url:String,method:HTTPMethod,parameters : [String:AnyObject]?,completionHandler:@escaping (JSON?,String)->Void) {

    let url = try! URLRequest(url: url, method: .post, headers: nil)
    Alamofire.upload(multipartFormData:{ multipartFormData in
        if  let imageData = UIImageJPEGRepresentation(image, 0.6) {
            multipartFormData.append(imageData, withName: "image", fileName: "Profile.png", mimeType: "image/png")
        }
        for (key, value) in parameters! {
            multipartFormData.append(value.data(using: String.Encoding.utf8.rawValue)!, withName: key)
        }
        }, with: url, encodingCompletion: {
            encodingResult in
            switch encodingResult {
            case .success(let upload, , ):
                upload.uploadProgress(closure: { (progress) in
                    print("Upload Progress: \(progress.fractionCompleted)")
                })
                upload.responseJSON { response in
                    if(response.result.isSuccess){
                        if let data = response.result.value{
                            let json = JSON(data)
                            print(json)
                            completionHandler(json,String())
                            return
                        }
                    }else {
                        completionHandler(nil,(response.result.error?.localizedDescription)!)
                    }
                    }

            case .failure( _):

                break
            }
    })
}
