# createItem The app intent conforms to the schema for creating an item on a whiteboard canvas. ``` var createItem: some AssistantSchemas.Intent { get } ``` ## Overview Use Swift macros that generate additional properties and add protocol conformance for your app intent implementation. The following example shows an app intent that conforms to the `.whiteboard.createItem` schema: ```swift @AppIntent(schema: .whiteboard.createItem) struct CreateCanvasItemIntent: AppIntent { @Parameter var target: CanvasEntity @Parameter var itemType: CanvasItemType? @Parameter var text: String? @Parameter var mediaItems: [IntentFile] @Parameter var url: URL? func perform() async throws -> some ReturnsValue { .result(value: CanvasItemEntity()) } } ``` For more information about the `.whiteboard` app intent domain, see [Whiteboard](/documentation/AppIntents/app-schema-domain-whiteboard).
