Scheduled notifications using AWS SNS

I am developing an iOS application using AWS for the first time. Most things are straightforward, but I'm having trouble finding out how to plan an alert in the future. I am currently using AWSSNSPublishInput to send push immediately, but there seems to be no way to schedule a notification for some time in the future. I would just use UILocalNotification to plan for a future notification, but I need to schedule a notification for another user.

For example, user A performs an action that user B should know the next day.

Does anyone have any ideas?

Amazon Simple Notification Service (SNS) is designed to send notifications immediately. There are no functions for scheduling notifications in SNS.

Amazon Simple Queue Service (SQS) has a delay function, but only up to 15 minutes - this is useful if you need to do some work before processing a message, for example, copying related data to Amazon S3.

Given that you need to schedule a notification for some future time. you need to implement server-side logic, for example, polling a database at a fixed fixed time interval OR something like a task scheduler .
