If I was creating a multi-platform code that includes storyboards for iOS and macOS, for example, I would mark each storyboard to its respective platform, the iOS storyboard to the iOS target and the Mac storyboard to the mac platform.
So I have zillions of files that are common to both platforms and these two storyboards, one for iOS and one for macOS.
How do I do that when I create a Swift Package?
