Programmatically UITableView using swift

Question

I'm trying to create a simple tableView programmatically using swift, so I wrote this code on "AppDelegate.swift" :

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {     self.window = UIWindow(frame: UIScreen.mainScreen().bounds)      var tvc :TableViewController = TableViewController(style: UITableViewStyle.Plain)     self.window!.rootViewController = tvc      self.window!.backgroundColor = UIColor.whiteColor()     self.window!.makeKeyAndVisible()     return true     } 

Basically I added the TableViewController creation and added to the window. And this is the TableViewController code:

class TableViewController: UITableViewController {  init(style: UITableViewStyle) {     super.init(style: style)  }  override func viewDidLoad() {     super.viewDidLoad()  }  override func didReceiveMemoryWarning() {     super.didReceiveMemoryWarning()     // Dispose of any resources that can be recreated. }  // #pragma mark - Table view data source  override func numberOfSectionsInTableView(tableView: UITableView?) -> Int {     return 1 }  override func tableView(tableView: UITableView?, numberOfRowsInSection section: Int) -> Int {     return 10 }   override func tableView(tableView: UITableView?, cellForRowAtIndexPath indexPath: NSIndexPath?) -> UITableViewCell? {     var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("reuseIdentifier", forIndexPath: indexPath) as UITableViewCell      cell.textLabel.text = "Hello World"      return cell } 

}

So, when I try to run the code I receive this message:

Xcode6Projects/TableSwift/TableSwift/TableViewController.swift: 12: 12: fatal error: use of unimplemented initializer 'init(nibName:bundle:)' for class 'TableSwift.TableViewController'

The error occurs when the compiler is executing the

super.init(style: style)

Any thoughts ?

In Xcode 6 Beta 4

Removing

init(style: UITableViewStyle) {     super.init(style: style) } 

will do the trick. This is caused by different initializer behavior between Obj-C and Swift. You have created a designated initializer. If you remove it, all initializers will be inherited.

The root cause is probably in -[UITableViewController initWithStyle:] which calls

[self initWithNibName:bundle:] 

I actually think this might be a bug in the way Obj-C classes are converted to Swift classes.
