Hello everyone. After months of development, I made a framework that helps you sync Realm Database with CloudKit. (Without touching Realm Object Server.)
It is called IceCream.
It just works like magic! And more important, it has been open sourced now! The first day it has reached 2nd place on the GitHub Swift trending page.

I wish more guys can join me and make IceCream much stronger. Also, I wonder if Realm Community could have a support on this project.
