 CoreDataRepository is a reactive library (Combine) for using CoreData on a background queue. It features endpoints for CRUD, batch, fetch multiple, and aggregate operations. Also, it offers a stream like subscription function for wrapping a fetch multiple call that will send updates that match the fetch request.
