I have written an app, using Swift 2 and Core Data for persistence, that is close to finished. I am thinking about adding a feature to also persist in the cloud. I have read tutorials on Realm and CloudKit, but haven't seen great examples on using them on top of (or along with) Core Data.
#1: I simply want to allow users to enter their data once and have it appear on all their devices.
#2: I also want them to be able sync some of their data with a user of their choice.
Can I keep all my Core Data logic and simply add some server calls during CRUD operations using CloudKit (or some other framework)?
Any help appreciated!
