WWDC swift student challenge

Hi,

I have done some iOS app programming using SwiftUI. I am interested in participating in the challenge. However, I am new to Swift playgrounds. Are there any tutorials on how to create an interactive playground ? Can I submit an app that I create or it has to be created with a playground ?

These were the rules for 2021:

Yes, must be playground.

You have a lot of Apple tutorials in Everyone can code in Apple Books.
