.navigationDestination(for: String.self){ selection in

    if(selection == "login"){
        Login(path: $path)
    }else if(selection == "register"){
        CreateAccount(path: $path)
    }
}
.onChange(of: path) { _ in
    
    if(path[path.count - 1] == "login" && path[path.count - 2] == "register"){
        // if current view is login  and the last one register, close register
        path.remove(path.count - 2)
    }
    
    if(path[path.count - 1] == "register" && path[path.count - 2] == "login"){
        // if current view is register  and the last one login, close login
        path.remove(path.count - 2)
    }
}

What I have inside onChange is non working pseudo code which should make it easier to understand what I need.

So basically I need to check which views are open and close specific ones.
