How to instantiate NSViewController in Swift?

Question

My current Swift code of

         var appBundle = NSBundle.mainBundle()
         let controller: ViewController = ViewController.init(nibName:        "ViewController", bundle: nil)
    self.window.contentView.addSubview(controller.view)
    controller.view.frame = self.window.contentView.bounds

is getting two errors. One is "Expected member name or constructor call after type name" and the other is "() is not convertible to 'ViewController'. For reference, ViewController is a class that inherits from NSViewController.

Both of the errors are occurring on the second line of code. Thanks in advance.

In swift you don't call init on classes to instantiate them. You leave out the init and just put the arguments right after the type name:

let controller = ViewController(nibName: "ViewController", bundle: NSBundle.mainBundle())

or, you shouldn't need to provide the nibName if it matches the name of the class:

let controller = ViewController()
