I am trying to draw smooth attached lines on ARSCNView, I have tried SCNNode and SCNSphere but it shows dotted line rather than single whole line. When I get my camera closer to the line it literally seems dotted and distributed

I have tried some accepted answers from other users but it does not produce what want, Please check my code below.

import UIKit
import ARKit

class DrawingView:UIViewController,ARSCNViewDelegate

 //MARK: Class properties
 lazy var sceneView:ARSCNView=
 let sv = ARSCNView()
 sv.delegate = self
 let panToDrawGesture = UIPanGestureRecognizer(target: self, action: #selector(createNodesFromPan(_:)))
 sv.addGestureRecognizer(panToDrawGesture)
 return sv
 ()

 //MARK: Lifecycle methods
 override func viewDidLoad() 
 super.viewDidLoad()
 self.setUpViews()
 

 override func viewWillAppear(_ animated: Bool) 
 super.viewWillAppear(animated)
 let configuration = ARWorldTrackingConfiguration()
 sceneView.session.run(configuration)
 


 override func viewWillDisappear(_ animated: Bool) 
 super.viewWillDisappear(animated)
 sceneView.session.pause()
 


 //MARK: Class methods

 func setUpViews()
 self.view.backgroundColor = .lightGray

 self.title = "Drawing"

 self.view.addSubview(sceneView)
 sceneView.frame = self.view.frame

 


 //MARK: Other methods

 @objc func createNodesFromPan(_ gesture: UIPanGestureRecognizer)

 let currentTouchPoint = gesture.location(in: self.sceneView)

 guard let featurePointHitTest = self.sceneView.hitTest(currentTouchPoint, types: .featurePoint).first else return 

 let worldCoordinates = featurePointHitTest.worldTransform

 let sphereNode = SCNNode()

 let sphereNodeGeometry = SCNSphere(radius: 0.005)
 sphereNodeGeometry.firstMaterial?.diffuse.contents = UIColor.blue
 sphereNode.geometry = sphereNodeGeometry

 sphereNode.position = SCNVector3(worldCoordinates.columns.3.x, worldCoordinates.columns.3.y, worldCoordinates.columns.3.z)
 self.sceneView.scene.rootNode.addChildNode(sphereNode)
 

I am trying to achieve smooth drawing lines which does not look dotted or distributed.
