Toolbar disappear after push

Question

I have FormViewController that I made full programmatically with Eureka form builder (link). I dont have view controller in storyboard for that. Class name of that view controller is NewPasswordVC. When I click od add bar button I open NewPasswordVC with this code:

let newPasswordVC = NewPasswordVC()
self.navigationController?.pushViewController(newPasswordVC, animated: true)

I open NewPasswordVC but when I go back in root view controller my bottom toolbar disappear. Why? How to fix this?

This is storyboard:

Answer 1

The solution to my problem I found here: link

override func willMove(toParent parent: UIViewController?){
    super.willMove(toParent: parent)
    if parent == nil{
        self.navigationController?.isToolbarHidden = false
    }
}

Answer 2

Can't speak about Eureka specifically, but chances are the UIViewController being pushed in has hidesBottomBarWhenPushed set to true.

So I would look into setting it to false, which can be done programmatically.
