Ensembles is an Objective-C synchronization framework for apps using Apple's Core Data.

Ensembles extends Apple's Core Data framework to add peer-to-peer synchronization for Mac OS and iOS. Multiple SQLite persistent stores can be coupled together via a file synchronization platform like iCloud or Dropbox. The framework can be readily extended to support any service capable of moving files between devices, including custom servers.
