# audiobook

An entity schema for an audiobook.

```
var audiobook: some AppSchemaEntity { get }
```

## Discussion

To make your app’s content available to Apple Intelligence, conform your [`AppEntity`](/documentation/AppIntents/AppEntity) to a schema that describes your content to the system. If your app’s functionality aligns with the `books` domain and its content matches the `audiobook` schema, you can generate the properties and protocol conformance the schema requires for your app entity implementation with the `@AppEntity( .books.audiobook)` Swift macro. To make your app work with Siri, see <doc://com.apple.documentation/documentation/AppIntents/apple-intelligence-and-siri-ai>.

The following example shows an app entity that conforms to the `audiobook` schema:

```swift
@AppEntity(schema: .books.audiobook)
struct AudiobookEntity {
    // MARK: Static

    static let defaultQuery = AudiobookEntityQuery()

    // MARK: Properties

    let id: <#Identifiable.ID#>

    var title: String?
    var seriesTitle: String?
    var author: String?
    var genre: String?
    var purchaseDate: Date?
    var url: URL?

    var displayRepresentation: DisplayRepresentation {
        <#DisplayRepresentation#>
    }

    // MARK: Query

    struct AudiobookEntityQuery: EntityQuery {
        func entities(for identifiers: [AudiobookEntity.ID]) async throws -> [AudiobookEntity] {
            <#code#>
        }
    }
}
```

The schema supports the following system experiences:
