# item

The app entity describes an item on a whiteboard canvas.

## Declaration

```swift
var item: some AssistantSchemas.Entity { get }
```

## Overview

Overview Use Swift macros that generate additional properties and add protocol conformance for your app entity implementation. The following example shows an app entity that conforms to the .whiteboard.item schema: @AppEntity(schema: .whiteboard.item) struct CanvasItemEntity: AppEntity {     struct Query: EntityStringQuery {         func entities(for identifiers: [CanvasItemEntity.ID]) async throws -> [CanvasItemEntity] { [] }         func entities(matching string: String) async throws -> [CanvasItemEntity] { [] }     }

static var defaultQuery = Query()     var displayRepresentation: DisplayRepresentation { "Canvas Item" }

let id = UUID()
