I've decided I want my app, which has been shipped to the App Store, to support CloudKit, but it's a .swiftpm app (so I could work on it on the go on an iPad and Swift Playgrounds).
I've taken a half-hearted stab at it (there's more pressing stuff to work on and this is a nice to have for the moment), but is there a way to set up a new workspace in Xcode where I have two targets: a .swiftpm version of the app and a .xcodeproj app so I can enable CloudKit for my app and also ship it to the App Store with the same identifier?
