# timerState

An enum schema for a timer state parameter.

## Declaration

```swift
var timerState: some AppSchemaEnum { get }
```

## Discussion

Discussion To make your app’s parameter types available to Apple Intelligence, conform your AppEnum to a schema that describes a parameter’s possible values to the system. If your app’s functionality aligns with the clock domain and a parameter type matches the timerState schema, you can generate the protocol conformance the schema requires for your app enum implementation with the @AppEnum( .clock.timerState) Swift macro. To make your app work with Siri, see Apple Intelligence and Siri AI. The following example shows an app enum that conforms to the timerState schema: @AppEnum(schema: .clock.timerState) enum TimerState: String {     case firing     case paused     case running     case undefined

static let caseDisplayRepresentations: [Self: DisplayRepresentation] = [         .firing: "Firing",         .paused: "Paused",         .running: "Running",         .undefined: "Undefined"     ] } 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.
