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()

    And you have to pass NSBundle.mainBundle() as bundle. Documentation says nil is ok, but atm you get error message if you trying to pass nil as bundle. – juniperi Jun 16 '14 at 03:45

    @juniperi you just saved me many more hours of frustration. I was trying to instantiate an NSViewController passing nil for the bundle and I kept getting a "Could not find an overload for '__conversion' that accepts the supplied arguments" error. Passing NSBundle.mainBundle() fixes this. Thanks – mike Jun 17 '14 at 14:50

I had to make the initialization of the view controller a global constant in order for it to work throughout my app. After racking my brain, I found that it was working locally, so making it global (putting it outside the AppDelegate class. works for me without the "nil" error) 

//global constant
let viewController = ViewController(nibName: "ViewController", bundle: NSBundle.mainBundle())

class AppDelegate: NSObject, NSApplicationDelegate {
    @IBOutlet var window: NSWindow

func applicationDidFinishLaunching(aNotification: NSNotification?) {

    //links and loads the view to the main window
    self.window.contentView.addSubview(viewController.view)
    viewController.view.frame = self.window.contentView.bounds

    //works locally and elsewhere as long as viewController is global!
    viewController.statusField.stringValue = "TESTING"
    println(viewController.statusField)

    } 
}

  • Also bundle: nil works too with the viewController constant is global. Apple's docs are not incorrect. This is on 10.9 anyways. nil loads the mainBundle according to the docs. and let controller = ViewController() also with it as a global with same class name. I've tested all three. – Goodtime Jul 08 '14 at 04:16
