iOS & Mac OS Local Notifications: Behind the Scene

How do local notifications work behind the scene in iOS? What does OS use to send it? Cron? Which core framework does it use?

I did't find any information about entrails of iOS 😟

Some notifications are time based and some are event based. On iOS, your app works with the system to deliver those to the user.


When the notification is time based, there is a count-down to a time/date in the future.


On macOS, your server does the heavy lifting.
