How to get data from a site for an application on SWIFT?

Question

iOS

Hello! Smart people, tell me which way to dig? There was a desire to make a diploma in application development for iOS. The bottom line is this: download the schedule from the university website and upload it to the application. So I don’t know how to communicate with this site itself. Tell me, please, what is used for this, what can I read? Thank you. Just in case, a link to the page with the schedule: ec.donstu.ru/site/ci/time_table/GroupTimeTable/25

Answer 1

Start digging towards the recruiting office.

Answer 2

Offtopic: Are you going to write a diploma and have no idea how data transfer works on the Internet? Something is not right here.
And now on the topic: Ideally, on the server with the schedule, you need to organize the REST API (if it does not exist).
I think this is enough to start googling.
