Ensembles Core Data iOS Framework by Drew McCormack Followers
The Ensembles Core Data iOS Framework by Drew McCormack aims to extend 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. It is written in Objective-C.
