Question

Hi. I am working on an educational app. I want

to send a notification to the user how long he studied every day at 22:00 and clear that time. Unfortunately iOS does not provide me anything like notification sent or not. I wanted to ask you guys have you encountered such problem? If yes how did you solve this ?

didReceive works on taps only. I am sending the time that the user studied every day at specific time. And when the user receives the notification I want to clear the cache.

hmmm, probably it’s not possible. but you can try to write studying time duration with a date. Check user last time studying and dayComponent of date is < current day -> clear and do it every app launching

yeah thank you for the suggestion and you time Andrii. I was doing the same for the past months but users send me report to the bug that. If they dont enter to the app after 22:00 the day after app sends them the time they listend yesterday this is the problem)

thank you Andrii. Yeah I tried this one too. The problem is when UNUserNotificationCenter.current().add(request) using this the time will be called once and never will be called after that. And that time will be called when you are adding the notification the the center

in theory you can schedule a background task to update your app’s cache after the notification appeared

not sure, try this, and set earliestBeginDate after the time your notification is supposed to fire https://www.andyibanez.com/posts/modern-background-tasks-ios13/
