hey guys, why these codes below doesn't work on iOS15? UINavigationBarAppearance *navBarApp =[UINavigationBarAppearance new]; [navBarApp configureWithTransparentBackground]; NSDictionary *dic = @{NSForegroundColorAttributeName : [UIColor redColor], NSFontAttributeName : [UIFont systemFontOfSize:20]}; navBarApp.titleTextAttributes = dic; self.navigationController.navigationBar.standardAppearance = navBarApp; how can i set the text color on the transparent navigationbar?
