How to find a touch's location in a node using location(in:)

Paul Hudson       @twostraws

It's just one line of code to find where the user touched the screen when you're using SpritKit, and that one line can even be used to calculative relative positions of a touch compared to any node in your game.

To get started, you should implement touchesBegan() in your SpriteKit node or scene. This will get called when the user starts touching the node, regardless of where on the node. To locate the exact position, call location(in:) on any UITouch, passing in the node you want to check, like this:

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