# board

The app entity describes a whiteboard canvas.

## Declaration

```swift
var board: 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.board schema: @AppEntity(schema: .whiteboard.board) struct CanvasEntity: AppEntity {     struct Query: EntityStringQuery {         func entities(for identifiers: [CanvasEntity.ID]) async throws -> [CanvasEntity] { [] }         func entities(matching string: String) async throws -> [CanvasEntity] { [] }     }

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