Answer 1

ARSCNView has a property 'pointOfView'. You can attach a child node to it.

let ball = SCNSphere(radius: 0.02)
ballNode = SCNNode(geometry: ball)
ballNode?.position = SCNVector3Make(0, 0, -0.2)
sceneView.pointOfView?.addChildNode(ballNode!)

The node will follow your camera anywhere you go.
