# stopwatch

An entity schema for a stopwatch.

## Declaration

```swift
var stopwatch: 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 stopwatch schema, you can generate the properties and protocol conformance the schema requires for your app entity implementation with the @AppEntity( .clock.stopwatch) 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 stopwatch schema: @AppEntity(schema: .clock.stopwatch) struct StopwatchEntity {     // MARK: Static

static let defaultQuery = StopwatchEntityQuery()

// MARK: Properties

let id: <#Identifiable.ID#>

var laps: [Duration]

var displayRepresentation: DisplayRepresentation {         <#DisplayRepresentation#>     }

// MARK: Query

struct StopwatchEntityQuery: EntityQuery {         func entities(for identifiers: [StopwatchEntity.ID]) async throws -> [StopwatchEntity] {             <#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.
