# updateItem

The app intent conforms to the schema for updating an item on a whiteboard canvas.

## Declaration

```swift
var updateItem: some AssistantSchemas.Intent { get }
```

## Overview

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.updateItem schema: @AppIntent(schema: .whiteboard.updateItem) struct UpdateCanvasItemIntent: AppIntent {     @Parameter     var target: CanvasItemEntity

@Parameter     var color: CanvasColor?

@Parameter     var label: String?
