ARKit - Issue with ARSession

Question

I'm trying to create ARSession, using ARKit with Xcode 9 beta (for iOS 11). But it seems not working properly.

Code I've tried is:

override func viewDidLoad() {

    super.viewDidLoad()

    // configure session
    let configuration = ARWorldTrackingSessionConfiguration()
    configuration.planeDetection = .horizontal

    // run session
    sceneView.session.run(configuration)
}

Can anyone help? Code is almost correct according to Apple Documentation.

Answer 1

You have problem with View controller's life cycle. According to apple guideline for ARSession, it Session can after you view is loaded completely. I mean, user view will appear to run your session.

Here is apple document for the same: Building a Basic AR Experience

Also, look at following sample.
