테이블에 동적으로 데이터 추가하기

현재 날짜를 가져와 행에 추가하는 코드 

import UIKit


class TableViewController: UIViewController, UITableViewDelegate, UITableViewDataSource{
    
    @IBOutlet weak var tableView: UITableView!
    let cellIdentifier: String = "cell"
    
    let korean: [String] = ["가","나","다","라","마","바","가","나","다","라","마","바"]
    
    let english: [String] = ["A","B","C","D","E","F","A","B","C","D","E","F"]
    
    override func viewDidLoad(){
        super.viewDidLoad()
        
        self.tableView.delegate = self
        self.tableView.dataSource = self
     }
    
    // 섹션을 몇개를 보여줄지?
    func numberOfSections(in tableView: UITableView) -> Int {
        return 2
    }
    
    // 섹션마다 무엇을 보여줄지?
    func tableView(_ tableView: UITableView, numberOfRowsInSection section:
      Int)->Int{
        
        switch section{
        case 0:
            return korean.count
        case 1:
            return english.count
        default:
            return 0
        }
    }
    
    // 줄에 해당하는 셀보여주기
    func tableView(_ tableView: UITableView, cellForRowAt indexPath:
                    IndexPath)-> UITableViewCell{
        
        let cell : UITableViewCell =
            tableView.dequeueReusableCell(withIdentifier: self.cellIdentifier,
            for: indexPath)
        
        let text: String = indexPath.section == 0 ? korean[indexPath.row] :
            english[indexPath.row]
        
        cell.textLabel?.text = text
        
        return cell
    }
