OneSignal is a leading push notification service provider that enables developers to send notifications to users across different platforms, including iOS, Android, and web. It simplifies the process of engaging users by providing a robust API for sending personalized and timely notifications.
When using OneSignal, you might encounter an issue where notifications are not being delivered to certain devices. One common symptom of this problem is receiving an error message indicating an 'Expired Push Token'. This error suggests that the push token associated with a device is no longer valid.
A push token is a unique identifier assigned to a device by the operating system (iOS or Android) that allows OneSignal to send notifications to that specific device.
Push tokens can expire for several reasons, including:
An expired push token means that any notifications sent to that token will not reach the intended device, leading to a breakdown in communication with the user.
To resolve the issue of an expired push token, follow these steps:
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { granted, error in
guard granted else { return }
DispatchQueue.main.async {
UIApplication.shared.registerForRemoteNotifications()
}
}
