In this episode, we fix the settings view using the Combine framework. We no longer rely on the delegation pattern to propagate settings changes. In the previous episode, we created a view model for the settings view controller. The settings view model exposes a publisher for each setting. Objects interested in settings changes can subscribe to these publishers. Let me show you how that works.
