Hiding Edit Menu of a SwiftUI / MacOS app

Question

My MacOS app doesn't have any text editing possibilities. How can I hide the Edit menu which is added to my app automatically? I'd prefer to do this in SwiftUI.

I would expect the code below should work, but it doesn't.

@main
struct MyApp: App {

var body: some Scene {
    WindowGroup {
        ContentView()
    }.commands {
        CommandGroup(replacing: .textEditing) {}
    }
}

}

For native (Cocoa) apps

It is possible to remove application menus using an NSApplicationDelegate. This approach may break in future macOS versions (e.g. if the position of the Edit menu were to change), but does currently work:

class MyAppDelegate: NSObject, NSApplicationDelegate, ObservableObject {
  let indexOfEditMenu = 2
   
  func applicationDidFinishLaunching(_ : Notification) {
    NSApplication.shared.mainMenu?.removeItem(at: indexOfEditMenu)
  }
}


@main
struct MyApp: App {
  @NSApplicationDelegateAdaptor private var appDelegate: MyAppDelegate

  var body: some Scene {
    WindowGroup {
      ContentView()
    }.commands {
      // ...
    }
  }
}

For Catalyst (UIKit) apps

For Catalyst-based macOS apps, the approach is similar to that above, except that a UIApplicationDelegate deriving from UIResponder is used:

class MyAppDelegate: UIResponder, UIApplicationDelegate, ObservableObject {
   override func buildMenu(with builder: UIMenuBuilder) {
      /// Only operate on the main menu bar.
      if builder.system == .main {
         builder.remove(menu: .edit)
      }
   }
}


@main
struct MyApp: App {
  @UIApplicationDelegateAdaptor private var appDelegate: MyAppDelegate

  var body: some Scene {
    WindowGroup {
      ContentView()
    }.commands {
      // ...
    }
  }
}
