title: How to automatically delete push notifications from iOS notification centre at a specific time?
body: <p>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).</p>
  <p>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.</p>
  <p>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.</p>
  <p>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?</p>
