I have a UITabBarController to whose controllers I would like to attach navigation. So I inserted the NavigationController as the entry controller, and the tabBarController as its root. All seems working fine, but for the tabBar. Basically it does not show, albeit the StoryBoard I attach seems to say differently. I also attach the Account Screen not showing any navigation bar nor, of course, any back button.

Thanks,
Fabrizio
