i am creating cloudkit based app where i have to create database structure. I got stuck in CKReference. How i can use CKReference for creating a good database structure
"Design the CloudKit schema to store the portions of your app’s object model that you want to persist. If you are implementing an app from scratch, use the Model-View-Controller design pattern to separate the user interface views from the model objects. Then design a schema that efficiently stores the portions of the object model you want to store in iCloud."
Try these links (the second one likely answers your question directly):
