# draft

The app entity describes an email draft.

```
var draft: some AssistantSchemas.Entity { get }
```

## 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 `.mail.draft` schema:

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

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

    let id = UUID()

    @Property
    var to: [IntentPerson]

    @Property
    var cc: [IntentPerson]

    @Property
    var bcc: [IntentPerson]

    @Property
    var subject: String?

    @Property
    var body: AttributedString?

    @Property
    var attachments: [IntentFile]

    @Property
    var account: MailAccountEntity
}
```
