An intent schema that navigates to the next or previous page.
To make your app's actions available to Apple Intelligence,
conform your ``AppIntent`` to a schema that describes your action to the system.
If your app's functionality aligns with the `books` domain
and one of your app's actions matches the `navigatePage` schema,
you can generate the properties and protocol conformance the schema requires
for your intent implementation
with the `@AppIntent( .books.navigatePage)` 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 intent that conforms to the `navigatePage` schema:
```swift
@AppIntent(schema: .books.navigatePage)
struct NavigateBookPageIntent {
var direction: <#BookNavigationDirection#>
var target: <#BookEntity#>
func perform() async throws -> some IntentResult {
<#code#>
}
}
