If you want to hide your iOS tabbar, just as you're displaying your macOS toolbar, this is what you can do in your SceneDelegate:

     func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {

         #if targetEnvironment(UIKitForMac)

         if let windowScene = scene as? UIWindowScene {

             if let titlebar = windowScene.titlebar {

                 let toolbar = NSToolbar(identifier: \"NerauToolbar\")



                 let rootViewController = window?.rootViewController as? UITabBarController

                 rootViewController?.tabBar.isHidden = true



                 toolbar.delegate = self

                 titlebar.titleVisibility = .hidden



                 titlebar.toolbar = toolbar

             }

         }

         #endif

     }
