How do you verify if an object or area has been hit in an application?

To check if a point is inside an object or area in iOS, methods involving UIView geometry or Core Graphics are usually used.
For example, to check if a point is inside a UIView, you can use the point(inside:with:) method:
let point = CGPoint(x: 50, y: 50)
if myView.point(inside: point, with: nil) {
print("Point is inside the view")
} else {
print("Point is outside the view")
}
If you need to check for a more complex area, you can use UIBezierPath and the contains(_:) method:
let path = UIBezierPath(ovalIn: CGRect(x: 0, y: 0, width: 100, height: 100))
let point = CGPoint(x: 50, y: 50)
if path.contains(point) {
print("Point is inside the oval")
}
Thus, the hit test reduces to using built-in methods to determine if a point belongs to an area.
