A big thank you to all of you. My application is compiling, now there is a problem: The content of my json file does not appear I do not know why. Here is the link of the json file. https://drive.google.com/file/d/1qMKLNcf1fvYla21Yhh_D36FuPI-0-kj2/view?usp=drivesdk here is the code to display the chapters but I don't know why nothing is displayed https://drive.google.com/file/d/1BFUzbk0fQB2mLotmvGPsS1FBkZlRIzSB/view?usp=sharing that's my ChaptersViewController please help me

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 }
