How to add a UITableView Programmatically in a single function without using UITableViewDataSource in Swift

import UIKit



class ViewController: UIViewController{

    let cellIdentifier = "Cell"
    override func viewDidLoad() {

        let screenSize = UIScreen.mainScreen().bounds
        let screenHeight = screenSize.height
        let screenWidth = screenSize.width


        var tableView = UITableView(frame: (CGRectMake(0, 0, screenWidth, screenHeight)), style: UITableViewStyle.Grouped)
        tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: cellIdentifier)
        tableView.numberOfRowsInSection(5)
        var indexPath = NSIndexPath()
        let cell : UITableViewCell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as UITableViewCell
        cell.textLabel!.text = "hello WOrld"
        tableView.indexPathForCell(cell)
        view.addSubview(tableView)
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
