How does one display a new view controller in the same Mac window?

Question

I\'m fairly new to Mac development and am slightly confused by the new \"storyboard\" feature in Xcode 6. What I\'m trying to do is segue from one view controller to another

Answer 1

Simple way with no segues involved to replace the current view controller in the same window:

if let myViewController = self.storyboard?.instantiateController(withIdentifier: "MyViewController") as? MyViewController {
    self.view.window?.contentViewController = myViewController
}
