How to load JSON data into cells using Alamofire/SwiftyJSON?

Question

I have a link to this JSON that I need to populate cells with the data inside it. It's basically a questions and answers array.

I've tried several solutions on the internet but none seem to adjust to my need.

This is some of the code that I gathered but I don't think it will serve me well.

var preguntas = [String]()

func getPreguntas(url: String, parameters:[String:String]) {
        Alamofire.request(url, method: .get, parameters: parameters).responseJSON { response in

            if response.result.isSuccess {
                print("Success!")
                let preguntasJSON: JSON = JSON(response.result.description)
            } else {
                print("Error \(String(describing: response.result.error))")
            }
            self.tableView.reloadData()
        }
    }

func updatePreguntas(json: JSON) {
    for (pregunta, respuesta) in json["faqs"] {
        let preg = ("\(pregunta) \(respuesta)")

            preguntas.append(preg)
        }
    }

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: FAQTableViewCell.reuseIdentifier, for: indexPath)

        if let cell = cell as? FAQTableViewCell {
            // TODO
            cell.preguntaLabel.text = preguntas[indexPath.row]
//            cell.respuestaLabel.text = respuestas[indexPath.row]
        }

        return cell
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return preguntas.count
    }

What I need is to have the preguntas as title of the cells and on tap have the respuestas show below while expanding the cell. But I've got the expanding part covered. But I can't get those two things from the JSON.

Use Codable

var preguntas = [String]()


Alamofire.request(URL(string:"https://test-tokbox-assistcard.herokuapp.com/faqs")!, method: .get, parameters: [:], encoding: URLEncoding.default, headers: [:]).responseData { response in


    if response.result.isSuccess {

        guard let data = response.data else { return }

        do {

         let res = try JSONDecoder().decode(Empty.self, from: data)
         print(res.faqs)
         preguntas = res.fags.map { $0.pregunta }
        }
        catch {

            print(error)
        }
    }
    self.tableView.reloadData()
}

// MARK: - Empty
struct Empty: Codable {
    let faqs: [FAQ]
}

// MARK: - FAQ
struct FAQ: Codable {
    let pregunta, respuesta: String
}
