How can you set boundaries for touch handling on a UIView element?

To set touch handling boundaries on a UIView, you can override the point(inside:with:) method. This method determines whether a touch point is inside the area where the UIView should respond to touches. By default, it checks if the point lies within the bounds.
Here's an example of overriding to expand the touch area by 20 points around the view:
override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
let margin: CGFloat = 20
let largerBounds = bounds.insetBy(dx: -margin, dy: -margin)
return largerBounds.contains(point)
}
Thus, you can decrease or increase the responsive touch area by setting your own boundaries.
