# updateAlarm

An intent schema that updates the alarm, for example, turn on / off the alarm, change the label, time, or repeating schedule.

```
var updateAlarm: some AppSchemaIntent { get }
```

## Discussion

To make your app’s actions available to Apple Intelligence, conform your [`AppIntent`](/documentation/AppIntents/AppIntent) to a schema that describes your action to the system. If your app’s functionality aligns with the `clock` domain and one of your app’s actions matches the `updateAlarm` schema, you can generate the properties and protocol conformance the schema requires for your intent implementation with the `@AppIntent( .clock.updateAlarm)` 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 `updateAlarm` schema:

```swift
@AppIntent(schema: .clock.updateAlarm)
struct UpdateAlarmIntent {
    var alarm: <#AlarmEntity#>
    var isEnabled: Bool?
    var time: DateComponents?
    var label: String?
    var recurrenceDays: Calendar.RecurrenceRule?
    var allowsSnooze: Bool?

    func perform() async throws -> some ReturnsValue<<#AlarmEntity#>> {
        <#code#>
    }
}
```

The schema supports the following system experiences:

- Siri
- Shortcuts
