Update: I also tried this code, but even then no result. It doesn't display anything and yet it compiles without any problem class ViewController: UIViewController { struct ContentView : View { var body: some View { VStack { Text("Google Mobile Ads") GADBannerViewController() } } } // MARK: - Setting Google View Mobile Ads struct GADBannerViewController : UIViewControllerRepresentable{ func makeUIViewController(context: Context) -> some UIViewController { let view = GADBannerView(adSize: GADAdSizeBanner) let viewController = UIViewController() let testID = "ca-app-pub-3940256099942544/2934735716" view.adUnitID = testID view.rootViewController = viewController // viewController.view.addSubview(view) viewController.view.frame = CGRect(origin: .zero, size: GADAdSizeBanner.size) //Load Ads view.load(GADRequest()) //view.backgroundColor = .secondarySystemBackground return viewController }
