[ios] How to check if a view controller is presented modally or pushed on a navigation stack?

Swift 5
Here is solution that addresses the issue mentioned with previous answers, when isModal() returns true if pushed UIViewController is in a presented UINavigationController stack.

extension UIViewController {
    var isModal: Bool {
        if let index = navigationController?.viewControllers.firstIndex(of: self), index > 0 {
            return false
        } else if presentingViewController != nil {
            return true
        } else if navigationController?.presentingViewController?.presentedViewController == navigationController {
            return true
        } else if tabBarController?.presentingViewController is UITabBarController {
            return true
        } else {
            return false
        }
    }
}

It does work for me so far. If some optimizations, please share.
