# appEntityIdentifier(forSelectionType:identifier:)

Associates the items in a SwiftUI list view with app entities to make them discoverable by Apple Intelligence and Siri.

```

## Discussion

Discussion Use this modifier to make app entities that describe data in a list discoverable by Apple Intelligence and Siri. This provides additional context to the system when the list appears onscreen and people scroll through it. The following example associates a List view that displays books with an app entity for each book in the list. struct BookListView: View {    let books: [Book]    @State private var selection = Set<Book.ID>()    var body: some View {        List(selection: $selection) {            ForEach(books) { book in                BookView(book.name)            }        }        .appEntityIdentifier(forSelectionType: Book.ID.self) { bookId in            EntityIdentifier(for: Book.self, identifier: bookId)        }    }  } For more information, refer to doc:Making-onscreen-content-available-to-siri-and-apple-intelligence and App Intents.
