What action does a hit test perform?

Hit Test in iOS is used to determine whether a touch point (for example, from a user) is within the bounds of a specific interface element (UIView or its subclasses).

This helps to understand which element was tapped or touched, so that the event can be handled correctly.

For example: if a user taps on the screen, the system checks which of the visible elements contains that point and passes the event to that element.

In code, it might look like this:

let point = gestureRecognizer.location(in: view)
if view.hitTest(point, with: nil) != nil {
    // Touch point inside view
}
