I'm looking through all the latest posts to clarify a doubt I have, I noticed @eskimo's response claiming that the app must be built and run on iPadOS 16 or later. So I suppose it's okay to create an app that has SwiftData as the framework even if that dictates that the app will run on iOS 17; Also because when you create a new project in Swift Playgrounds 4.4.1 (latest version available at the moment) the target is set to iOS 17.2 automatically and technically you can't edit Package.swift file manually.
Thanks in advance ❤️
