var book: 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 .books.book schema:

@AppEntity(schema: .books.book)
struct BookEntity: AppEntity {
    struct Query: EntityStringQuery {
        func entities(for identifiers: [BookEntity.ID]) async throws -> [BookEntity] { [] }
        func entities(matching string: String) async throws -> [BookEntity] { [] }
    }

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

    let id = UUID()

    @Property

    @Property

}
