When make pop to NavigationController, Parent view controller hide

Question

The settings that I have is:

UINavigationController -> RootParentViewController

Then ParentViewController have a UIContainerView. There I load dynamically content (Other's UIViewController Child).

When I make a transition from:

UINavigationController -> RootParentViewController (ChildViewController) -> Another ChildViewController

Using (it's working):

self.navigationController?.pushViewController(subCategoryViewController,   animated: true)

I created my custom Back button (reason of design), But when I call:

self.navigationController?.popViewControllerAnimated(true)

It's popping to the ChildViewController although is calling the viewDidAppear of RootParentViewController (is like hide the parent)

Answer 1

I got it,

The problem is, that I was setting navigationBarHidden in the childViewController. Then when I made pop, navigation continue hidden.
