    let navigationController = UINavigationController(rootViewController: documentController)
    // Open an existing local file URL.
    let fileURL: URL! = Bundle.main.url(forResource: "sample", withExtension: "pdf")
    documentController.openDocument(with: fileURL)
    // Show navigation (and document) controller.
    self.present(navigationController, animated: true, completion: nil)
