I have created ARSCNView programmatically as the below code. The app runs on my real iPhone (without crashing) but shows a blank/black screen. It doesn't ask for accessing the camera either (I have the line "Privacy - Camera Usage Description" in Info.plist already). With the commented line sceneView.backgroundColor = .green
I am sure the ARSCNView is created, added, and full screen.
import ARKit
class ViewController: UIViewController {
let sceneView = ARSCNView()
override func viewDidLoad() {
super.viewDidLoad()
sceneView.frame = self.view.frame
self.view.addSubview(sceneView)
// make sure the sceneView is added and full screen
//sceneView.backgroundColor = .green
}
}
You need to add SCNScene to your ARSCNView
let scene = SCNScene()
sceneView.scene = scene
And start ARWorldTrackingConfiguration in viewWillAppear
//Inside view will appear
let config = ARWorldTrackingConfiguration()
self.sceneView.session.run(config)
