问题
I am developing an iOS app using Swift which has push notification feature. The app sends Birthday reminders notifications to the users via push notifications (APNS used here).
Currently, the push notification remains in the device's notification center until the user taps on that notification or opt to clear it from the device.
Now I am looking for a way to automatically delete that push notification at the end of every day as there is no need of showing past day's birthday notifications in the device.
Can someone suggest me a solution that in which way I can implement this? Is it possible to delete notification from iOS without having any user interaction?
Thanks in advance.

@dm_mobile Your question is 100% valid.
In order to remove the specific notification from the Notification center automatically, - you can't do that from the iOS side, until and unless user interact with that notification - But, you can do that from the server side, let me tell you how
How to remove notification from the notification center programmatically?
When server send you any notification via APNS server using the APNS endpoint, the APNS will return you some data as a payload, you will get the notification identifier as a apns-id key in the response header
Store that apns-id value in your database table at the server side.
At the end of day or with specific condition criteria, you can delete that notification from the device's notification center by sending another request to APNS by Passing the apns-id value in the request header.
Skype is doing the same thing.
