iOS swift popToRootViewController fire function in rootViewController

In my app I go back to rootViewController via:

self.navigationController?.popToRootViewController(animated: true)

Now i want to call a function from my rootViewController only when i come back using popToRootViewController. Is there a possibility for this?

The easiest way to go about it is to get a reference to the root view controller via navigationController.viewControllers[0] before the call to popToRootViewController(animated:), set a boolean flag on it and then use the value of that flag in the root view controller's viewDidAppear.

Alternatively, you could use the same approach with UINavigationControllerDelegate.navigationController(_:didShow:animated:), though I'm not entirely sure whether it will be called after popping the controllers programmatically.
