    let configuration = ARWorldTrackingConfiguration()

    override func viewDidLoad() {
        super.viewDidLoad()

推荐答案

如果你只是问如何添加 ARSCNView，那么我的回答是:

If you are just asking about how to add ARSCNView, then my answer would be:

//instantiate scene view in viewDidLoad
sceneView = ARSCNView()

//add it to parents subview
self.view.addSubview(sceneView)

//add autolayout contstraints
sceneView.translatesAutoresizingMaskIntoConstraints = false
sceneView.topAnchor.constraint(equalTo: self.view.topAnchor).isActive = true
sceneView.leftAnchor.constraint(equalTo: self.view.leftAnchor).isActive = true
sceneView.rightAnchor.constraint(equalTo: self.view.rightAnchor).isActive = true
sceneView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor).isActive = true

//load your scene
