# listType

An enum schema for a list type parameter.

## Declaration

```swift
var listType: 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 reminders domain and a parameter type matches the listType schema, you can generate the protocol conformance the schema requires for your app enum implementation with the @AppEnum( .reminders.listType) 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 listType schema: @AppEnum(schema: .reminders.listType) enum ListType: String {     case standard

static let caseDisplayRepresentations: [Self: DisplayRepresentation] = [         .standard: "Standard"     ] } 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.
