func prepare(for segue: UIStoryboardSegue, sender: Any?)

guard let nextViewController: WeatherViewController = segue.destination as? WeatherViewController else {

            return

} // segue.destination - 데이터 도착지

 guard let cell: UITableViewCell = sender as? UITableViewCell else {

            return

}// sender 데이타 보내는 곳 설정

 

 nextViewController.country = cell.textLabel?.text

 

도착지에 country이라는 변수에  cell.textLabel?.text을 전달..
