How to drag an image view within a window using swift (OS X not IOS)

I am creating a Mac application but having difficulty when dragging a window with an image on the view. Basically I can drag the main window but unable to drag the window when clicking and dragging the image view.

I can enable dragging on the main window with "window.movableByWindowBackground = true" seems to work but unable to get this working when dragging the image view on the window.

enter image description here

Any help would be greatly appreciated.

The trick is to subclass your NSImageView and override the mouseDownCanMoveWindow property:

class MyImageView: NSImageView {

    override var mouseDownCanMoveWindow:Bool {
        return true
    }

}
