Example code for Table View in Swift

SwiftTable

import UIKit

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
                            
    override func viewDidLoad() {
        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.
    }
    
    func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int {
        return 10
    }
    
    
    func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {
        let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "MyTestCell")
        
        cell.text = "Row #\(indexPath.row)"
        cell.detailTextLabel.text = "Subtitle #\(indexPath.row)"
        
        return cell
    }


}

    super.viewDidLoad()

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 10;
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell: UITableViewCell = UITableViewCell(style: .Subtitle, reuseIdentifier: "MyTestCell")

    cell.textLabel?.text = "Row #\(indexPath.row)"
    cell.detailTextLabel?.text = "Subtitle #\(indexPath.row)"

    return cell
}

}

Above worked for me too. At first I put a IBOutlet just for trying it. then after I read the thread, I deleted it and tried, it still works. I think previous XCode 6 Betas might needed an IBOutlet. only thing I've connected is UITableViewDataSource and UITableViewDelegate.

Note: My XCode version is Version 6.3.2 (6D2105) running on Mac OS X Yosemite (10.10.3 (14D136))
