title: How to reset tab (or tab controller) of UITabBarController when user select tab?
body: <p>Swift: I have UITabBarController, with 8 tabs. When user select any tab including more tab, I want reset content of selected tab by Popping to rootView controller?</p>
  
  <p>How could this be done?</p>
  
  <p>I tried to reset navigation controllers in below methods, It works for tabs which are visible at bottom but it doesn't work for <code>More</code> tab.</p>
  
  <pre><code>tabBarController(_ tabBarController: UITabBarController, didSelect viewController: UIViewController) 
  
  override func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem)
  </code></pre>
