Swift PHP how to correctly send parameter to my php

Hi so i have some probleme to send some parameters to my php.

when my php don't take post :

<?php
require_once "connIOS.php";
require_once "validate.php";

$email =validate($_POST['id']);
$mdp = validate($_POST['password']);


$sql = 'SELECT `Cl_Email`,`Cl_mdp` FROM `clients` WHERE `email`="myemail@gmail.com" AND `password`= "1234"';
// Check if there are results
if ($result = mysqli_query($con, $sql))
{
  // If so, then create a results array and a temporary one
  // to hold the data
  $resultArray = array();
  $tempArray = array();
 
  // Loop through each row in the result set
  while($row = $result->fetch_object())
  {
    // Add each row into our results array
    $tempArray = $row;
    array_push($resultArray, $tempArray);
  }
 
  // Finally, encode the array to JSON and output the results
  echo json_encode($resultArray);
}
 
// Close connections
mysqli_close($con);
?>

i get in my swift log :

[{"email":"myemail@gmail.com","password":"1234"}]

but i get nothing when my request SQL take the post

here is my swiftcode :

import UIKit
import Alamofire

class ViewController: UIViewController {
   
  @IBOutlet weak var idTextField: UITextField!
  @IBOutlet weak var passwordTextField:UITextField!
   
  @IBAction func forgotPasswordButton(_ sender: UIButton) {
  }
   
  @IBAction func loginButton(_ sender: UIButton) {
     
    var id:NSString = idTextField.text! as NSString
    var password:NSString = passwordTextField.text! as NSString
    var urlLink = "http://domain.com/myPHP.php"
     
    if(id.isEqual(to:"") || password.isEqual(to: "")){
      print("id ou mdp vide")
      let alert = UIAlertController(title: "", message: "identifiant ou mot de passe incorrecte", preferredStyle: .alert)
      alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { action in
        switch action.style {
        case .default:
          print("default")
        case .cancel:
          print("cancel")
        case .destructive:
          print("destructive")
        @unknown default:
          fatalError()
        }
      }))
      self.present(alert, animated: true, completion: nil)
    }else{
      print("reussite")
       
      let parameters = ["id":"\(id)","password":"\(password)"]
       
      var sParams = ""
       
      for (key,value) in parameters{
       //http://domain.com/Appli/myPHP.php ? parameter1Key = parameter1Value & parameter2Key = parameter2Value
        sParams += key + "=" + (value as String) + "&"
        print("\(key),\(value as String)")

      }
      if !sParams.isEmpty{
        sParams = "?" + sParams
        
        if sParams.hasSuffix("&"){
          sParams.removeLast()
          
        }
         
        urlLink = urlLink + sParams
      }else{
        print("!sParams.isEmpty fail")
      }

      let serializer = DataResponseSerializer(emptyResponseCodes: [200,204,205])
       
      var request = URLRequest(url : URL(string:urlLink)!)
      AF.request(request).uploadProgress{progress in }.response(responseSerializer: serializer){ response in
        if response.error == nil {
          var responseString: String!
           
          responseString = ""
           
          if response.data != nil {
            responseString = String(bytes:response.data!, encoding: .utf8)
           
             
          }else{
            responseString = response.response?.description
           
          }
           
          print(responseString ?? "")
          print(response.response?.statusCode as Any)
          var data : NSData!
           
          if let data = data {
            //Succeed
            let dataLength = data.length
            print("Size: \(dataLength) Bytes")
          }else{
            //print(data)
          }
         
          
          print("response time: \(response.metrics?.taskInterval.duration ?? 0)")
        }
      }
       
    }
  }
   
  @IBAction func signInButton(_ sender: UIButton) {
  }
   
   
  override func viewDidLoad() {
     
    super.viewDidLoad()
    // Do any additional setup after loading the view.
