Answer 1

I used this code in my app with Swif 3+

    var userInfo = notification.userInfo
    if let keyboardFrame = (userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue{
        print(keyboardFrame.height)
        if keyboardFrame.size.height <= 0 { // To fix bug on iOS 11
            if let newKeyboardFrame = (userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue{
                print(newKeyboardFrame.height)
            }
        }
    }
    view.layoutIfNeeded()
