Unbalance Calls Warning on Modal Present then Navigation Pop to Root in Completion

Take the below code (called from any given view controller in a navigation stack).

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    let vc = MyViewController()
    present(vc, animated: true) {
        self.navigationController?.popToRootViewController(animated: false)
    }
}

Now, this works perfectly well and everything behaves as expected. However, I get the following warning.

Unbalanced calls to begin/end appearance transitions for <MyApp.MyViewController: 0x1044276d0>.

So, given the warning printed, is there a better way to have a user be at the root of a navigation stack when they dismiss a modal view controller presented from any given view controller in the navigation stack?

you can try delegate. From ViewDidAppear method of view controller being presented – rv7284 May 30 '18 at 05:22
where you called this `let vc = MyViewController()` in page load or else – Anbu.Karthik May 30 '18 at 05:22
