# init(newDocument:editor:) Creates a document group for creating and editing file documents. ``` @preconcurrency nonisolated init(newDocument: @autoclosure @escaping @Sendable () -> Document, @ContentBuilder editor: @escaping (FileDocumentConfiguration) -> Content) ``` ## Parameters `newDocument` The initial document to use when a user creates a new document. `editor` The editing UI for the provided document. ## Discussion Use a `DocumentGroup` scene to tell SwiftUI what kinds of documents your app can open when you declare your app using the `App` protocol. You initialize a document group scene by passing in the document model and a view capable of displaying the document’s contents. The document types you supply to `DocumentGroup` must conform to `FileDocument` or `ReferenceFileDocument`. SwiftUI uses the model to add document support to your app. In macOS this includes document-based menu support including the ability to open multiple documents. On iOS this includes a document browser that can navigate to the documents stored on the file system and multiwindow support: ``` @main struct MyApp: App { var body: some Scene { DocumentGroup(newDocument: TextFile()) { file in ContentView(document: file.$document) } } } ``` The document types you supply to `DocumentGroup` must conform to `FileDocument` or `ReferenceFileDocument`. Your app can support multiple document types by adding additional `DocumentGroup` scenes. With the `newDocument:` initializer, SwiftUI considers your app as an editor of documents of given content types (`FileDocument.writableContentTypes`). On macOS, this adds a File > New menu item and enables the standard document commands. On iOS, it shows a New Document button in the document browser. The `FileDocumentConfiguration/isEditable` property is `true`. Use the `DocumentGroup/init(viewing:editor:)` initializer instead if your app should only display documents without modifying them. --- Copyright © 2026 Apple Inc.
