How to allow a Tab Bar Item to have multiple view controllers

I've been stuck on this problem for a few days now and any help would be appreciated.

I have a UITabBarController that has four TabBarItems.

I want to determine what view controller is displayed to the user depending on whether the user is logged in.

For example when the user is not logged in, I want to display different login screen depending on which TabBarItem is selected - each login will look different. When the user is logged in I want to display normal content the selected TabBarItem

I was thinking of having multiple ViewControllers for each tab bar item. When a user selects a TabBarItem, determine if the user is logged in and then display the correct ```ViewController. I'm not sure if this is the right approach and how to achieve this behaviour.

Update: This is the solution I have come up with but was wondering what everyone thinks - whether it's the right approach. This is what my Storyboard looks like: enter image description here

The idea is when the user is logged in I would show the login view controllers and when the user is not logged in I would show the logged out view controllers.

I would be using the self.present(...) to change to and from the login and logout ViewControllers.

You can change your displayed tabs with setViewControllers. Simply set the array of desired viewControllers when user logs in or logs out.

class TabBarController: UITabBarController {
    func onMyLogin() {
        setViewControllers(myNormalViewControllers, animated: false)
    }
    func onMyLogout() {
        setViewControllers(myUnidentifiedViewControllers, animated: false)
    }
}
