Error in Silent notification display banner in Objective c iOS 11

Question

I am implementing Silent notification in Objective c Code in ios 11. Using FCM Notification by adding this method. What is Silent Push Notification? When does the device receive it?

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler
{

   //Success
    handler(UIBackgroundFetchResultNewData);
}

and paylod is :

    {
    "aps" = {
        "content-available" : 1,
        "sound" : ""
    };
    // You can add custom key-value pair here...
}

didReceiveRemoteNotification method call when notification recived But my question is why banner is visible when silent notification receive. How to restrict notification banner.

Remove extra keys from aps array and payload should be like this.

"aps" = {
    "content-available" : 1
};
