When I navigate to the view controller containing ARSCNView a blank screen appears

Question

When I navigate to the view controller containing ARSCNView a blank screen appears instead of camera view, with all other UI Elements visible partially (transparent)

This is my code for navigating to the next ViewController

let

secondViewController = storyboard?.instantiateViewController(withIdentifier: "SecondViewController") as! SecondViewController
self.present(secondViewController, animated: true, completion: nil)

Answer 1

Since ARSCNView uses camera you have to add permission request in plist file. Add "Privacy - Camera Usage Description" in order to be able to use camera.
