# itemType

The type of an item on a whiteboard canvas.

## Declaration

```swift
var itemType: some AssistantSchemas.Enum { get }
```

## Overview

Overview Use Swift macros that generate additional properties and add protocol conformance for your app enum implementation. The following example shows an app enum that conforms to the .whiteboard.itemType schema: @AppEnum(schema: .whiteboard.itemType) enum CanvasItemType: AppEnum {     case square     case circle

static var caseDisplayRepresentations: [CanvasItemType: AppIntents.DisplayRepresentation] = [         .square: "Square",         .circle: "Circle",     ] } For more information about the .whiteboard app intent domain, see doc:Making-whiteboard-actions-available-to-siri-and-apple-intelligence.
