The WWDC requirements say:
Submissions will be judged offline. Your Swift playground should not rely on a network connection and any resources used in your Swift playground should be included locally in your ZIP file.
So how is it possible to connect to databases to access stored data? I'm confused since last year's winning project (https://www.apple.com/newsroom/2021/06/apples-wwdc21-swift-student-challenge-winners-code-to-change-the-world/) seemed to have had to use an online connection (for its matching volunteers to individuals system). Or is it simply that I submit an app with data internally stored (but that seems weird to me)? If that is the case, do I even need to code a framework to send data to a database?
