CloudKit is a framework for storing and retrieving data on Apple’s iCloud servers. Queries can be run against structured records on the server, and assets provide for large data storage.

CloudKit also provides a user identity so that an iCloud account can be used for sign-in for your app.

CloudKit is a transfer mechanism rather than a full sync solution, but it can be used to build custom syncing solutions.
