# activity

An enum schema for an activity parameter.

## Declaration

```swift
var activity: 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 audio domain and a parameter type matches the activity schema, you can generate the protocol conformance the schema requires for your app enum implementation with the @AppEnum( .audio.activity) 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 activity schema: @AppEnum(schema: .audio.activity) enum AudioActivity: String {     case cooking     case dining     case studying     case focusing     case reading     case gaming     case working     case showering     case cleaning     case relaxing     case sleeping     case indoorActivity     case partying     case commuting     case driving     case traveling     case gardening     case barbecuing     case beachDay     case roadTrip     case outdoorActivity     case meditating     case yoga     case walking     case running     case strength     case cycling     case dance     case hiit     case rowing     case workoutLowIntensity     case workoutMediumIntensity     case workoutHighIntensity
