[question]: Trying to capture notification payload from OneSignal

[arbyruns]

How can we help?

I'm attempting to capture the incoming notification, but I'm unable to hit my breakpoints within UNUserNotificationCenterDelegate. How would I go about capturing the notification from OneSignal?

extension AppDelegate: UNUserNotificationCenterDelegate {
    // Called when a notification is delivered to a foreground app.
    nonisolated func userNotificationCenter(_ center: UNUserNotificationCenter,
                                willPresent notification: UNNotification,
                                withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

        // Log the notification content
        let userInfo = notification.request.content.userInfo
        logger.info("Notification received in foreground: \(userInfo)")

        // You can also display an alert, sound, or badge
        completionHandler([.banner, .sound, .badge, .list])
    }

    // Called when a notification is opened
    nonisolated func userNotificationCenter(_ center: UNUserNotificationCenter,
                                didReceive response: UNNotificationResponse,
                                withCompletionHandler completionHandler: @escaping () -> Void) {

        // Log the notification content when it's opened
        let userInfo = response.notification.request.content.userInfo
        logger.info("Notification opened: \(userInfo)")

        completionHandler()
    }
}

Having the same issue can't get any UNUserNotificationCenterDelegate methods to trigger.

I'm most probably missing a step when configuring the library but i can't figure out what is it

Might've figured it out, the UNUserNotificationCenter delegate must be assigned after OneSignal's initialization like so

OneSignal.initialize("oneSignalAPIKey", withLaunchOptions: launchOptions)
UNUserNotificationCenter.current().delegate = self

🤪

@mirko-milovanovic-vidiemme I was able to get it working by following https://documentation.onesignal.com/docs/mobile-sdk-reference#addforegroundlifecyclelistener.

Update: actually that appears to be only when the app is in the foreground.

you have to implement a Notification Service Extension to always get the notification payload.
Example here:
https://github.com/OneSignal/OneSignal-iOS-SDK/blob/main/iOS_SDK/OneSignalDevApp/OneSignalNotificationServiceExtension/NotificationService.m

For background pushs (without a visible notification), there is an extra setup needed to get the payload.
