ARKit -使用raycastQuery代替hitTest的Tap节点，已弃用

import ARKit

class ViewController: UIViewController, ARSCNViewDelegate {
    @IBOutlet var sceneView: ARSCNView!

    override func viewDidLoad() {
        super.viewDidLoad()
        sceneView.delegate = self
    }

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        guard let touchLocation = touches.first?.location(in: sceneView) else { return }
        let raycastQuery = ARRaycastQuery(origin: sceneView.pointOfView!.position, direction: sceneView.pointOfView!.forward)
        let results = sceneView.session.raycast(raycastQuery)

        if let result = results.first {
            let node = result.node
            print("Tapped node: \(node.name ?? "")")
        }
    }
}
