Access all data in a CoreData store as a developer

Hello

I am building a study research app that tracks data of different users. The data is saved through Core Data (with relationships) and I was wondering if there was a way to view all the data through CloudKit?

I know I can use public databases with CloudKit in CoreData but was wondering if that would merge all the data of the different users, and if that is the case how would I deal with it?

If that is not possible how would I download all the data in a PDF that the user can send?

Thanks for your help

Implement a feature in the app the users can use to share the data with you (email attachment of some kind)?. Or app uses HTTP to upload data to a server managed by you? Using ResearchKit, if your app is a research app?
