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 ?

Hi, I am new to Playground (I know Swift and Objective-C a bit) but can't seem to figure out to how to create a new playground . Can someone point me to a simple tutorial ?
