For the Swift Student Challenge it says that it must run on MacOS or iPadOS as a Swift Playgrounds App. I have been working on an iOS app in XCode as a Swift Playgrounds App. I assumed MacOS just meant we were working on the app on Mac XCode which in hindsight could be a massive misinterpretation.
I know we have to use Swift Playgrounds App. Do we have to create a Mac app or an it be an iPhone app that runs on the XCode simulator on a Mac? And if it is an iPhone app that runs on a simulator, is there a specific iPhone simulation being used? The description specifies that iPadOS must be optimized for all models- does that imply that an iOS does not have to?
