Get data from payload when remote push notification arrive while my app is in background or closed

Question

I need to capture data from payload when recive a remote push notification, on IOS 9 i did this using the func: didReceiveRemoteNotification On IOS 10 using swift 3.0 i've implemented this 2 functions.

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)
{
print("\(notification.request.content.userInfo)")

completionHandler([.alert, .badge, .sound])
}

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)
{
print("User Info = ",response.notification.request.content.userInfo)

completionHandler()
}

the second fuction only executes when the user touch the push

i need capture data when a push notification arrives while my app is in background or even closed.

Regards. greetings

When a push notification is received and your app isn't running, you need to implement your notification logic in didFinishLaunchingWithOptions:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
   // Called when a notification is tapped and the app wasn't running, not in foreground neither in background. 
   if let userInfo = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? [String: AnyObject]{
        // your logic here!
    }
}
