Customize the File Name Menu in the Toolbar of a DocumentGroup Window

Forums > SwiftUI

I'm currently working on a Document based App and have successfully implemented saving and reading from a file.

I want to customize the Toolbar of the Document Window, which shows the filename. In particular I want to hide the files extension and add a line below the filename.

The documentation gave me this:

 ContentView()
    .navigationTitle("My Title")
    .navigationDocument(
        myDocument, 
        preview: SharePreview(
            "My Preview Title", image: myDocument.image))

I wrapped the ContentView inside my DocumentGroup View – but this does not seem to work for me. I know that I could potentially just remove the filename entirely by .windowToolbarStyle(.unified(showsTitle:false)) but I want the menu and drag functionality of this.

Maybe some one has an idea what to keep in mind or what did I read wrong from the docs.
