Get on the right path! How to make notifications?

Question

iOS

Good afternoon! I delve into the development on Swift'e under ios. It is necessary to send notifications to the user daily at the time that he enters in my program. I got lost in a lot of literature in English ... Do I need some kind of server to send notifications to everyone? And if a person does not have the Internet, will he be left without important information? Is it really impossible to register my notification in some Notification Center on the device and issue it, as if by cron?
I apologize for my ignorance, there is too little time for learning, because. immediately have to be developed to order.

Look at swiftbook.ru/content/koposhilka/local-notification...
There you can only change the interval trigger to a trigger by date, you can also add a badge.
