# timer

An entity schema for a timer.

## Declaration

```swift
var timer: some AppSchemaEntity { get }
```

## Discussion

Discussion To make your app’s content available to Apple Intelligence, conform your AppEntity to a schema that describes your content to the system. If your app’s functionality aligns with the clock domain and its content matches the timer schema, you can generate the properties and protocol conformance the schema requires for your app entity implementation with the @AppEntity( .clock.timer) Swift macro. To make your app work with Siri, see Apple Intelligence and Siri AI. The following example shows an app entity that conforms to the timer schema: @AppEntity(schema: .clock.timer) struct TimerEntity {     // MARK: Static

static let defaultQuery = TimerEntityQuery()

// MARK: Properties

let id: <#Identifiable.ID#>

var duration: Duration     var durationRemaining: Duration     var state: <#TimerState#>     var label: String?     var isSleepTimer: Bool

var displayRepresentation: DisplayRepresentation {         <#DisplayRepresentation#>     }

// MARK: Query

struct TimerEntityQuery: EntityQuery {         func entities(for identifiers: [TimerEntity.ID]) async throws -> [TimerEntity] {             <#code#>         }     } } The schema supports the following system experiences: Siri Shortcuts For more information about the App Intents framework and the experiences it supports, see Getting started with the App Intents framework.
