ARKitにジェスチャー機能を実装

Question

前提・実現したいこと

ARKitを利用した家具アプリを作りたいのですが
gestureを追加したところ反応はされているのですが
描画が一切変わらず困っています

該当のソースコード

let panGesture = UIPanGestureRecognizer(target: self, action: #selector(doPan))
        let rotationGesture = UIRotationGestureRecognizer(target: self, action: #selector(doRotation))
        let pinchGesture = UIPinchGestureRecognizer(target: self, action: #selector(doPinch))
        self.sceneView.addGestureRecognizer(panGesture)
        self.sceneView.addGestureRecognizer(rotationGesture)
        self.sceneView.addGestureRecognizer(pinchGesture)


 @objc
    private func doPan(sender: UIPanGestureRecognizer) {
        let point = sender.location(in: self.sceneView)
        print("point = (point)")
        let results = sceneView.hitTest(point, types: .existingPlaneUsingExtent)
        if let hitPoint = results.first {
            guard let node = sceneView.pointOfView else { return }
            let vector = SCNVector3(
                x: hitPoint.worldTransform.columns.3.x,
                y: hitPoint.worldTransform.columns.3.y,
                z: hitPoint.worldTransform.columns.3.z
            )
            node.position = vector
        }
    }
    
    @objc
      private func doRotation(sender: UIRotationGestureRecognizer) {
          guard let node = sceneView.pointOfView else { return }
        print("rotation = (node)")
          node.runAction(SCNAction.rotateBy(x: 0, y: sender.rotation-3, z: 0, duration: 0.1))
      }
    
    @objc
    private func doPinch(gesture: UIPinchGestureRecognizer) {
        let scale = Float(gesture.scale)
        guard let node = sceneView.pointOfView else { return }
        
        switch gesture.state {
        case .changed:
            print("pinch = (scale)")
            //ノードのスケールを拡大・縮小
            if scale > 1.000000000 {
                let action = SCNAction.scale(by: CGFloat(10), duration: 1)
                node.runAction(action)
            } else {
                let action = SCNAction.scale(by: CGFloat(10), duration: 1)
                node.runAction(action)
            }
            
        default:
            NSLog("not action")
        }
    }
    

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        
        guard let touch = touches.first else {return}
        
        let touchPos = touch.location(in: sceneView)
        
        let hitTest = sceneView.hitTest(touchPos, types:
        .existingPlaneUsingExtent)
        
        if !hitTest.isEmpty {
        // タップした箇所が取得できていればanchorを追加
        let anchor = ARAnchor(transform: hitTest.first!.worldTransform)
            sceneView.session.add(anchor: anchor)
        }
    }

試したこと

CGFloatの値を変更しましたが変わらず
他の方のソースコードを参考にしましたがそちらでも動きませんでした
