How to find a touch's location in a view with location(in:)

Swift version: 5.1

Paul Hudson    @twostraws   

When the user starts touching an iOS screen, touchesBegan() is immediately called with a set of UITouches. If you want to find where the user touched, you need to take one of those touches then use location(in:) on it, like this:

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    if let touch = touches.first {
        let position = touch.location(in: view)
        print(position)
    }
}

That will make position a CGPoint representing where the user touched in the current view. You can if you want pass a different view to location(in:), and it will tell you where the touch was relative to that other view instead.
