You can now use UIView.transition. Note that animated:false. This works with any transition option, pop, push, or stack replace.

if let nav = self.navigationController
{
    UIView.transition(with:nav.view, duration:0.3, options:.transitionCrossDissolve, animations: {
        _ = nav.popViewController(animated:false)
    }, completion:nil)
}
