Ok, Thank you for the clarifications.

For reducing the cost expense for sending push notification using Amazon SNS, we are scheduling local notifications. When i get a single silent notification, i will schedule 64 local notifications like the above code in for loop. But if i send all the 64 notifications as push notification, it will cost more. Hence, I am looking for a way to trigger scheduling location notification even when the app is quit from app switcher.

I am calling the below code for scheduling local notification whenever i receive a silent push notification.      let request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger)     let center = UNUserNotificationCenter.current()     center.add(request) { (error : Error?) in I need to call the above set of code even when app is quit from App Switcher.

@mungbeans Thank you for the quick reply. To reduce cost on Amazon SNS, in one silent notification, i will be scheduling 64 local notifications. Do you have any idea about how can i schedule local notification even after user quit app from App Switcher? Please advise, Thank you.
