At the end over every "how to adopt SwiftData in a CoreData app" it says, now go ahead and delete the xcdatamodeld files.
But my xcdatamodeld contains all the migrations necessary to even support SwiftData in the first place.
If I have 10 versions of my CoreData model, and the 10th matches the first version of my SwiftData model... But a user is on the 7th version, and then upgrade to the new app that doesn't contain any xcdatamodeld files..
How are you actually supposed to handle this? I don't want to keep supporting both. I just want to use SwiftData.
