Type ‘NSNotification.Name’ has no member ‘keyboardDidShowNotification’
I believe you use it like this now. NotificationCenter.default.addObserver( self, selector: #selector(self.keyboardDidShow(notification:)), name: UIResponder.keyboardDidShowNotification, object: nil) /* You can substitute UIResponder with any of it’s subclass */ It is listed in UIResponder doc as a Type Property.
