didReceiveRemoteNotification not working Swift

    }

    }

    }

Everything works fine with sending push notification to other device and even popup notification coming if we send message directly from Firebase account. But didReceiveRemoteNotification is not getting called while receiving notification.

回答1:

Try this:

func userNotificationCenter(_ center: UNUserNotificationCenter,  willPresent notification: UNNotification, withCompletionHandler   completionHandler: @escaping (_ options:   UNNotificationPresentationOptions) -> Void) {
    print("Handle push from foreground")
    // custom code to handle push while app is in the foreground
    print("\(notification.request.content.userInfo)")
 }

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    print("Handle push from background or closed")
    // if you set a member variable in didReceiveRemoteNotification, you  will know if this is from closed or background
    print("\(response.notification.request.content.userInfo)")
}

Add this code to your app delegates before that you have to add two notification framework in your application.

1.UserNotificationUI.framework 2.UserNotification.framework
