在缩放手势期间获取RealityKit实体的宽度和深度

let pinchGesture = UIPinchGestureRecognizer(target: self, action: #selector(handlePinch(_:)))
arView.addGestureRecognizer(pinchGesture)

@objc func handlePinch(_ gesture: UIPinchGestureRecognizer) {
    guard let entity = arView.scene.anchors.first?.children.first as? Entity else { return }
    
    if gesture.state == .changed {
        let scale = gesture.scale
        let width = entity.scale.x * scale
        let depth = entity.scale.z * scale
        
        // 打印宽度和深度
        print("宽度：\(width)，深度：\(depth)")
    }
}
