Switch TabBar Item from separate Navigation Controller

In my application I have TabBar Controller and Navigation Controller with one View Controller that are not connected to each other.

I use TabBar Controller as root vc in my app, and other Navigation Controller as a side menu which slides in on top of TabBar Controller. To make menu I used this repo - SideMenu

Question: How can I switch TabBar item from that Menu I have? Simply calling tabBarController?.selectedIndex = 1 inside MenuViewController does nothing.

In my app I have MainTabBarController which is almost always is root. I use static variable to access shared one.

class MainTabBarController: UITabBarController, UITabBarControllerDelegate {
    // MARK: - Variables
    public static var shared: MainTabBarController? {
        set {
            UIApplication.shared.window.rootViewController = newValue
        }

        get {
            guard let mainTabBarController = UIApplication.shared.window.rootViewController as? MainTabBarController else { return nil }

            return mainTabBarController
        }
    }
}

So I can change it any time.

MainTabBarController.shared?.selectedIndex = 0

Simply calling tabBarController?.selectedIndex = 1 inside MenuViewController does nothing.

This shouldn't work, because of your hierarchy.
