ARKit image detection, add image - swift

Question

I'm using ARKit 1.5 (beta) for image detection. Once I detect my image I would like to then place a AR scene image using the plane detected. How can this be done?
My code so far which detects the image (which is in my assets folder):
/// - Tag: ARImageAnchor-Visualizing
func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor) {
guard let imageAnchor = anchor as? ARImageAnchor else { return }
let referenceImage = imageAnchor.referenceImage
updateQueue.async {
// Create a plane to visualize the initial position of the detected image.
let plane = SCNPlane(width: referenceImage.physicalSize.width,
height: referenceImage.physicalSize.height)
let planeNode = SCNNode(geometry: plane)
planeNode.opacity = 0.25
/*
`SCNPlane` is vertically oriented in its local coordinate space, but
`ARImageAnchor` assumes the image is horizontal in its local space, so
rotate the plane to match.
*/
planeNode.eulerAngles.x = -.pi / 2
/*
Image anchors are not tracked after initial detection, so create an
animation that limits the duration for which the plane visualization appears.
*/
planeNode.runAction(self.imageHighlightAction)
// Add the plane visualization to the scene.
node.addChildNode(planeNode)
}
DispatchQueue.main.async {
let imageName = referenceImage.name ?? ""
self.statusViewController.cancelAllScheduledMessages()
self.statusViewController.showMessage("Detected image “\(imageName)”")
}
}
var imageHighlightAction: SCNAction {
return .sequence([
.wait(duration: 0.25),
.fadeOpacity(to: 0.85, duration: 1.50),
.fadeOpacity(to: 0.15, duration: 1.50),
.fadeOpacity(to: 0.85, duration: 1.50),
.fadeOut(duration: 0.75),
.removeFromParentNode()
])

Assuming that referenceImage.name's value is the actual image filename.
if let imageName = referenceImage.name {
plane.materials = [SCNMaterial()]
plane.materials[0].diffuse.contents = UIImage(named: imageName)
}
