Global Notifications

On top of reactive publishers exposed by some components, VideoKit offers a variety of global notifications sent through NSNotification that give you the flexibility to react on certain events.

You can subscribe through the notification center:

NotificationCenter.default.addObserver(self, selector:  #selector(self.notificationHandler(_:)), name: .<NotificationName>, object: nil)
