Log("actObserver: Live Activity registered successfully") } } // Async monitoring private func registerPushTokenUpdates<T: SAKActivityAttributes>(...) { Task { self.pushTokenObserveRecords.safe{ $0.append(activity.id) } Log("Monitoring pushToken updates for Live Activity <\(activity.id)>") for await data in activity.pushTokenUpdates { let pushToken = pushTokenString(with: data) // Report token to APNS service reportTokenToAPNS(pushToken) } } } System Log Evidence System logs, log and log
