In the previous episode, you learned about publishers and subscribers. Combine creates a subscription when a subscriber is attached to a publisher. In the setupNotificationHandling() method of the RootViewModel class, the subscription is returned to the view model as an AnyCancellable instance. The view model holds on to the AnyCancellable instance to prevent the subscription from terminating early. We covered this in the previous episode.
