While an existing transition or presentation is occurring; the navigation stack will not be updated

Question

I have encountered this warning:

pushViewController:animated: called on while an existing transition or presentation is occurring; the navigation stack

Answer 1

I solved this using DispatchQueue.main.asyncAfter call popviewcontroller after the UIAlertController's Transition complete

1) Show Alert

2) Call pop viewcontroller after delay

DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
    self.navigationController?.popToRootViewController(animated: true)
}

This is not best way, but it works!
