So I'm trying to create a scene programmatically
class ViewController: UIViewController, ARSCNViewDelegate {
var sceneView: ARSCNView = ARSCNView()
let configuration = ARWorldTrackingConfiguration()
override func viewDidLoad() {
super.viewDidLoad()
self.sceneView.debugOptions = [ARSCNDebugOptions.showFeaturePoints, ARSCNDebugOptions.showWorldOrigin]
self.configuration.planeDetection = .horizontal
self.sceneView.session.run(configuration)
self.sceneView.delegate = self
self.sceneView.autoenablesDefaultLighting = true
self.sceneView.translatesAutoresizingMaskIntoConstraints = false
self.sceneView.topAnchor.constraint(equalTo: self.view.topAnchor).isActive = true
self.sceneView.leftAnchor.constraint(equalTo: self.view.leftAnchor).isActive = true
self.sceneView.rightAnchor.constraint(equalTo: self.view.rightAnchor).isActive = true
self.sceneView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor).isActive = true
}
func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor) {
guard anchor is ARPlaneAnchor else {return}
}
}
But I get this error message:
Application termination due to an undetected "NSGenericException" exception, reason: "It is not possible to activate the restriction using anchors and because they do not have a common ancestor. Is the restriction or its bindings related to elements in different presentation hierarchies? Is this illegal.
This happens in part \\add autolayout contstraints
. How to add restrictions to this element?
