ViewControllers that inherit from this class should be displayed as a popover or modal, with a button that binds to the IBAction `pop()`. To get the value of the popover during close, pass a callback function as the `dispose` parameter. The callback passed will have access to the `PlatformViewController` and all of it's properties at close so that the `count` can be passed back through the message channel if needed. */ class PlatformViewController: NSViewController { var count: Int = 0 var dispose: ((PlatformViewController)->())? @IBOutlet weak var label: NSTextField! var labelText: String { get { return "Button tapped \(self.count) time\(self.count != 1 ?
