Alamofire - ResponseJSON deprecated

Question

I'm using AlamoFire to communicate with my php/web-application and want to solve this annoying warning... My app is working fine but will become deprecated if i do not fix this.

.responseJSON { response in :

responseJSON(queue:dataPreprocessor:emptyResponseCodes:emptyRequestMethods:options:completionHandler:)' is deprecated: responseJSON deprecated and will be removed in Alamofire 6. Use responseDecodable instead.

public func authenticateUser(username: String, password: String, completion: @escaping (String) -> Void) {
        let url = "myAPI.com.br/api/Login"
        
        let parameters: Parameters = [
            "login": username,
            "password": password
        ]
        let headers: HTTPHeaders = [
            "Content-Type": "application/json"
        ]

        AF.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers)

        //FOR DEBUG ONLY
        //.validate()

            .responseJSON { response in

                //FOR DEBUG ONLY
               // print("Response JSON: \(response)")
                //print("Response Status Code: \(String(describing: response.response?.statusCode))")
                //print("Response HTTP Headers: \(String(describing: response.response?.allHeaderFields))")

                switch response.result {
                        //Em caso de sucesso na consulta -> retorno 200 -> salva o retorno da api dentro getContentFromAPI
                    case .success(let readContentFromAPI):

                        //Salva o conteudo retorno da api. Caso seja vazio cria dicionario padrão vazio
                        let savedDataFromAPI = (readContentFromAPI as? [String: Any]) ?? [:]

                        //Verifique se a API retornou success em status. /api/login -> echo json_encode(['status' => 'success', 'package' => $userData]);
                        if (savedDataFromAPI["status"] as? String == "success") {

                            //Armazena o dicionário tipo json ["Campo:Valor"] que retorna da api
                            let userPackage = savedDataFromAPI["userData"] as? [String: Any]

                            do {
                                //For save userData in application only
                                let data = try JSONSerialization.data(withJSONObject: userPackage!, options: .fragmentsAllowed)
                                let userData = try JSONDecoder().decode(UserData.self, from: data)

                                //Save userDate to application Session for later consulting
                                self.userData = userData

                                //Check if is a authorized user. If lvl 0, hold
                                //Only devs can change users groups
                                //This feature is a security feature
                                if (self.userData?.group_id == 0) {
                                    completion("Denied")
                                }
                                //Show homescreen if user is authorized
                                else {
                                    completion("Success")
                                }
                            } catch {
                                print("Error decoding user data: \(error)")
                            }
                        } else {
                            completion("Failure")
                        }

                    case .failure(let error):
                        completion("Error")
                        print("Request failed with error: \(error)")
                }
            }
    }

This is my API function:

public function login()
    {
        header('Content-Type: application/json');
        header('Access-Control-Allow-Origin: *');

        // Read POST request data
        $data = json_decode(file_get_contents('php://input'), true);
        $login = $data['login'];
        $hashedPass = $data['password'];

        $result = $this->model->authenticateUserAPI($login, $hashedPass);

        if ($result) {
            $userData = $this->model->loadAPISession($result);
            echo json_encode(['status' => 'success', 'userData' => $userData]);
        } else {
            echo json_encode(['status' => 'failed']);
        }
    }

I tried to change .responseJSON to .responseDATA and app stop to work like expected and another warning appears.

let savedDataFromAPI = (readContentFromAPI as? [String: Any]) ?? [:] -> Cast from 'Data' to unrelated type '[String : Any]' always fails

Any ideas how to fix this?

In recent Swift, it's recommended to use Codable struct. If you don't want to use modern features, you can still do manually with responseData, see https://stackoverflow.com/questions/70789753/update-responsejson-to-responsedecodable-in-swift/70804441#70804441 — Larme, Aug 28 '23 at 14:58
If you replaced blindly `responseJSON` with `responseData`, then `readContentFromAPI` is a `Data`, so you need to serialize it with `JSONSerialization` first... — Larme, Aug 28 '23 at 14:59
