Result which i got : enter image description here

here is the code i treid so far:

     let newCollection: UICollectionView = {
    let layout = UICollectionViewFlowLayout()
    let collection = UICollectionView(frame: CGRect(x: 0, y: 0, width: 200, height: 100), collectionViewLayout: layout)
    layout.scrollDirection = .horizontal
    collection.backgroundColor = UIColor.gray
    collection.translatesAutoresizingMaskIntoConstraints = false
    collection.isScrollEnabled = true
    return collection
}()

  func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor) {

    DispatchQueue.main.async {
        guard let imageAnchor = anchor as? ARImageAnchor,
            let imageName = imageAnchor.referenceImage.name else { return }

   self.newCollection.delegate = self
            self.newCollection.dataSource = self
            self.newCollection.register(MyCollectionViewCell.self, forCellWithReuseIdentifier: self.cellId)
            self.view.addSubview(self.newCollection)
            self.setupCollection()

            let collectionPlane = SCNPlane(width: 0.2, height: 0.1)
            collectionPlane.firstMaterial?.diffuse.contents = self.newCollection

            let collectionNode = SCNNode(geometry: collectionPlane)
            collectionNode.eulerAngles.x = -.pi/2
            collectionNode.runAction(SCNAction.moveBy(x: 0, y: 0, z: 0, duration: 0))

            node.addChildNode(collectionNode)


                   self.sceneView.scene.rootNode.addChildNode(node)


   }

      //collection view

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int
{
    return 7
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
{
    let cell = newCollection.dequeueReusableCell(withReuseIdentifier: cellId, for: indexPath) as! MyCollectionViewCell
    cell.backgroundColor = .blue
    return cell
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {

    return CGSize(width: 100, height: 50)
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {

    return UIEdgeInsets(top: 3, left: 3, bottom: 3, right: 3)
}

expected output: enter image description here

Set the material's diffuse's contents property to the collectionView's view property

let material = SCNMaterial()
material.diffuse.contents = yourCollectionView.view
