The purpose of using an abstract AnyObject type for an IBAction may be advantage for a situation in which you have multiple UI objects that should trigger the same action. An example of this would be if you wanted to have a button and a gesture recognizer share the functionality of a common action. Even with a shared action, it would be possible to have different execution paths for the two objects.

You can choose to use the parameter of
(sender: AnyObject)
or you can use(sender: UIButton)
.There might be times however where you might have to cast
AnyObject
as aUIButton
if you need access to the properties provided byUIButton
.For example let's say you have and you want the button to disappear after it is clicked.
