Browse to the initial_messages.json file in the friendlychat directory, select it then click the Import button. The list might display more details about each book (such as number of pages as well as the author's name), whereas the cover flow would display gorgeous book covers, with just the book title. To be able to use the view model in a SwiftUI view and subscribe to the data it manages, it needs to implement the ObservableObject protocol, and all properties that we want our UI to be able to listen to need to be flagged using the @Published property wrapper.
