Would like to be able to add previous screens to Navigation Stack

[Richard-Gist]

When trying to test the Back button on a view controller, I hit an issue in that UIViewController.loadFromStoryboard(identifier: storyboardIdentifier, forNavigation: true) worked for embedding my view in a navigation controller, but I also needed to have a previous view controller in the stack.

My workaround ended up looking like:

let viewController = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateViewController(identifier: storyboardIdentifier)
        (viewController as? NoteDetailViewController)?.note = note
        let navController = UINavigationController(rootViewController: UIViewController())
        navController.loadForTesting()
        navController.pushViewController(viewController, animated: false)
        RunLoop.current.singlePass()

There could be extra benefits if we could define what ViewControllers we wanted in the stack. If I could do that, then I could also test navigation backwards and that things function correctly in that scenario.
