Parse and mapping data in tableview with Alamofire and SwifrtJSON with completion handler(@escaping)

Question

I have data models. I make a request and get JSON. But I want to use the completion handler to add data to the table. How do I save data and display it in a tableview? I didn't use the entire data model for the test.

This is my data model

This is my function for parsing and mapping

class Network {
    let baseUrl = URL(string:"https://ppbet-327310.appspot.com/api/games")
    func getCity(completion: @escaping([WelcomeElement]) -> ()) {
        guard let url = baseUrl else {return}
        AF.request(url, method: .get).responseJSON { (response) in
            switch response.result {
            case .success:
                guard let data = response.data else {return}
                let json = try! JSON(data: data)
                let arrayCount = json.array?.count ?? 0
                for i in 0..<arrayCount {
                    let name = json[i]["name"].string ?? "N/A"
