IOS 10 push notifications - how willPresentNotification and didReceiveNotificationResponse function?

Question

Currently, I have installed an application for receiving push notifications in ios 9, where it works fine, but with iOS 10 I do not receive them. I looked at various answers on stackoverflow and came across this:

Push Notifications is not accepted on iOS 10, but works on iOS 9 and up

which seems to work for the poster. I'm not quite sure what code I should add under the willPresentNotification and didReceiveNotificationResponse sections. If anyone has examples of how these sections work, this will be appreciated. This is my corresponding code for handling push notifications:

import UserNotifications
import Whisper

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

  registerForPushNotifications(application)
}

 //MARK: Push Notification Settings
  func registerForPushNotifications(application: UIApplication) {

    //check to see if phone is updated to iOS 10
    if #available(iOS 10.0, *){
      UNUserNotificationCenter.currentNotificationCenter().delegate = self
      UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert], completionHandler: {(granted, error) in
        if (granted)
        {
          UIApplication.sharedApplication().registerForRemoteNotifications()
        }
        else{
          print("registering for push notifications unsuccessful")
        }
      })
    }

    else{ //If user is not on iOS 10 use the old methods we've been using
      let notificationSettings = UIUserNotificationSettings(
        forTypes: [.Badge, .Sound, .Alert], categories: nil)
      application.registerUserNotificationSettings(notificationSettings)

    }

  }

  //Notification handling for iOS 10
  @available(iOS 10.0, *)
  func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
    //Handle the notification - NOT SURE WHAT GOES HERE

  }

  @available(iOS 10.0, *)
  func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
    //Handle the notification -NOT SURE WHAT GOES HERE
  }


  //This is called if user selects to receive push notifications
  func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
    //    if notificationSettings.types != .None {
    application.registerForRemoteNotifications()
    //    }
  }

  func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
    var tokenString = ""

    for i in 0..<deviceToken.length {
      tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
    }

    //save device token to keychain
    self.deviceToken = tokenString
    userInfo.sharedInstance.savePushNotDeviceToken(tokenString)
    NSUserDefaultsManager.sharedManager.pushNotifications = true

    //register device token to api
    registerPushNotificationDevice(tokenString)

    print("Device Token:", tokenString)
  }


  func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    print("Failed to register:", error)

    //save push notifications state
    NSUserDefaultsManager.sharedManager.pushNotifications = false

  }


  //In- App push notifications
  func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    if application.applicationState == .Active {

      let navigationController = self.window!.rootViewController as! UINavigationController

      let alert = [String: String]()
      let title = ""
      let body = ""

      // Default printout of userInfo
      print("All of userInfo:\n\( userInfo)\n")

      if let aps = userInfo["aps"] as? NSDictionary {
        if let alert = aps["alert"] as? NSDictionary {
          if let title = alert["title"] as? NSString {
            if let body = alert["body"] as? NSString {

              let announcement = Announcement(title: title as String, subtitle: body as String, image: UIImage(named: "Image"))
                show(shout: announcement, to: navigationController)

            }
          }
        }
      }
    }
  }



}
