# documentKind

The file type for a document.

## Declaration

```swift
var documentKind: 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 .reader.documentKind schema: @AppEnum(schema: .reader.documentKind) enum ReaderDocumentKind: AppEnum, Codable {     case image     case pdf

static var caseDisplayRepresentations: [Self: DisplayRepresentation] {         [             .image: .init(title: "Image", image: .init(systemName: "photo")),             .pdf: .init(title: "PDF", image: .init(systemName: "doc.text")),         ]     } } For more information about the .reader app intent domain, see doc:Making-document-reader-actions-available-to-siri-and-apple-intelligence.
