  答案是： Yes, it's possible .

  使用以下代码完成它：

  import UIKit
  import SceneKit
  import ARKit
  
  class ViewController: UIViewController, ARSCNViewDelegate {
  
      @IBOutlet weak var sceneView: ARSCNView!
      @IBOutlet weak var sceneView2: ARSCNView!
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          sceneView.delegate = self
          sceneView.showsStatistics = true
          let scene = SCNScene(named: "art.scnassets/ship.scn")!
          sceneView.scene = scene
          sceneView.isPlaying = true
  
          // Setup for sceneView2
          sceneView2.scene = scene
          sceneView2.showsStatistics = sceneView.showsStatistics
  
          // Now sceneView2 starts receiving updates
          sceneView2.isPlaying = true     
      }
  
      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()
      }
      func renderer(_ renderer: SCNSceneRenderer, updateAtTime time: TimeInterval) {
          DispatchQueue.main.async {
              self.updateFrame()
          }
      }
      func updateFrame() {   
          // Clone pointOfView for Second View
          let pointOfView: SCNNode = (sceneView.pointOfView?.clone())!
  
          // Determine Adjusted Position for Right Eye
          let orientation: SCNQuaternion = pointOfView.orientation
          let orientationQuaternion: GLKQuaternion = GLKQuaternionMake(orientation.x, 
                                                                       orientation.y, 
                                                                       orientation.z, 
                                                                       orientation.w)
          let eyePos: GLKVector3 = GLKVector3Make(1.0, 0.0, 0.0)
          let rotatedEyePos: GLKVector3 = GLKQuaternionRotateVector3(orientationQuaternion, 
                                                                     eyePos)
          let rotatedEyePosSCNV: SCNVector3 = SCNVector3Make(rotatedEyePos.x, 
                                                             rotatedEyePos.y, 
                                                             rotatedEyePos.z)  
          let mag: Float = 0.064 // Interocular distance (in metres)
          pointOfView.position.x += rotatedEyePosSCNV.x * mag
          pointOfView.position.y += rotatedEyePosSCNV.y * mag
          pointOfView.position.z += rotatedEyePosSCNV.z * mag
  
          // Set PointOfView for SecondView
          sceneView2.pointOfView = pointOfView    
      }
  }
