Type 'NSNotification.Name' has no member 'keyboardDidShowNotification'

Question

I'm getting this error with Swift 4.2

Type 'NSNotification.Name' has no member 'keyboardDidShowNotification'

Here is my code:

NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardDidShow(notification:)), name: NSNotification.Name.keyboardDidShowNotification, object: nil) 

Following one was working fine with Swift 4 but not with Swift 4.2

NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardDidShow(notification:)), name: NSNotification.Name.UIKeyboardDidShow, object: nil) 

Apple document Ref: NSNotification.Name.keyboardDidShowNotification

Answer 1

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.
