When the keyboard rectangle appears, I would like to move my views. I worked from the best answer to this question to attempt to implement this in Swift.
When the program tries to get the UIKeyboardFrameEndUserInfoKey value it found nil. But if I cast this value to NSValue it HAS the value of NSRect type. If I try to cast it to NSRect I get an error "Undeclared type". If I cast it to CGREct I get nil. What's going on here?
