I can't understand your questions and your description. My problem was similar to this only.

CustomTabBarController -> CustomUINavigationController -> RootViewcontroller

viewWillAppear of CustomUINavigationController and RootViewController are not getting called unless you switched to another tab and come back.

The solution is call super.viewWillAppear(animated: true)

override func viewWillAppear(_ animated: Bool) {
    **super.viewWillAppear(true)**
}

I struggled for more than a day for this small mistake.
