You probably want to put your NavigationView inside your ContentView

Here's a concise example of my question... import SwiftUI @main struct DocumentApp: App {     var body: some Scene {         DocumentGroup(newDocument: DocumentDocument()) { file in             ContentView(document: file.$document)         }     } } struct ContentView: View {     @Binding var document: DocumentDocument     var body: some View {         VStack {             Button(action: {                 // TODO: Dismiss ContentView and show DocumentGroup browser             }) {                 Text("Close")             }             TextEditor(text: $document.text)         }     } }

You should probably be using CoreData for your SQLite storage. You could use a sqlite file with FileDocument, but you'd have to handle the reading and writing and management of that by yourself (which is what CoreData does). FileDocument is for documents, like a pages or numbers document or a file of some type (or a custom one that you create).

Also of note here is that the following code doesn't dismiss the view and the isPresented property is false in the ContentView presented by the DocumentGroup. @Environment(\.presentationMode) var presentationMode struct ContentView: View {     var body: some View { Button(action: { self.presentationMode.wrappedValue.dismiss() }) { Text("Dismiss") } } }

I've implemented a template picker by adding a template property to my FileDocument and checking it in the editor View and then optionally showing the template picker or the editor. This works well, but I don't see a way to dismiss the window back to the browser if they want to cancel out of the template picker.

You can also make a group of Scenes, but only the first one is displayed. I’d really like on iOS to transition from one scene to another (specifically a WindowGroup to a DocumentGroup) and on macOS to have the second scene to open in a new window. Why allow more than one scene per app if you can’t show one from a button click just like with Settings()?
