For the Swift 3 users, the @Hector code (with some additions) would be:

In your viewDidLoad add the observer :

NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardDidShow(_:)), name: .UIKeyboardDidShow , object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardDidHide(_:)), name: .UIKeyboardDidHide , object: nil)

Then implement those methods:

func keyboardDidShow(_ notification: NSNotification) {
     print("Keyboard will show!")
     // print(notification.userInfo)

     let keyboardSize:CGSize = (notification.userInfo![UIKeyboardFrameBeginUserInfoKey] as! NSValue).cgRectValue.size
     print("Keyboard size: \(keyboardSize)")  

     let height = min(keyboardSize.height, keyboardSize.width)
     let width = max(keyboardSize.height, keyboardSize.width)

}

func keyboardDidHide(_ notification: NSNotification) {
        print("Keyboard will hide!")
}
