On Silent Notification, swizzling on, application:didReceiveRemoteNotification:userInfo: not being triggered

[bennyd-intenthq]

Description

I sent a Silent Notification using firebase messaging api. Swizzling is on But the method application:didReceiveRemoteNotification:userInfo: not being triggered

Reproducing the issue

I sent a silent notification through https://fcm.googleapis.com/v1/projects/jedai-sdk/messages:send with the next body { "message": { "token": "FCM_TOKEN", "apns": { "headers": { "apns-priority": "5" // Use "5" for silent, background notifications }, "payload": { "aps": { "content-available": 1 } } }, "data": { "key1": "2", "key2": "value2" } } }

In my AppDelegate.swift I have the next implementation func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) { print("BennyDebug in didReceiveRemoteNotification \(userInfo)") completionHandler(.newData) }

When swizzling if off, the method being invoked. However when swizzling if on, this method not being called.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Thanks for reporting, @bennyd-intenthq. Could you confirm if you've tapped the notification so the didReceiveRemoteNotification will be called?

[bennyd-intenthq]

Hi @rizafran . Upon (non-silent) notification

1. The method didReceiveRemoteNotification is not called
2. The method func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) { being called.

[rizafran]

Hi @bennyd-intenthq, I was able to reproduce the issue. The didReceiveRemoteNotification will only be called when I removed the UNUserNotificationCenter.current().delegate = self. I'll consult this to our engineers to see if it's a bug or intended.
