# eventSpan

An enum schema for an event span parameter.

## Declaration

```swift
var eventSpan: 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 calendar domain and a parameter type matches the eventSpan schema, you can generate the protocol conformance the schema requires for your app enum implementation with the @AppEnum( .calendar.eventSpan) 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 eventSpan schema: @AppEnum(schema: .calendar.eventSpan) enum EventSpan: String {     case this     case future     case all

static let caseDisplayRepresentations: [Self: DisplayRepresentation] = [         .this: "This",         .future: "Future",         .all: "All"     ] } 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.
