Which component of the system handles gesture events in the application?

In iOS, the UIGestureRecognizer class and its subclasses, such as UITapGestureRecognizer, UIPinchGestureRecognizer, UISwipeGestureRecognizer, and others, are used to handle gesture events. These gesture recognizers can be added to any UIView to detect and handle corresponding user gestures.

Example of adding a tap recognizer to a button:

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap))
button.addGestureRecognizer(tapGesture)

@objc func handleTap() {
    print("Button was tapped")
}
