Ensembles is a local-first synchronization framework that extends Apple's Core Data to sync SQLite persistent stores across macOS and iOS devices via file-sync services like iCloud and Dropbox, or peer-to-peer connections, without a dedicated server. This Objective-C version is deprecated in favor of the Swift rewrite Ensembles 3.
Use cases
- sync core data between ios and mac devices
- offline-first app with core data sync
- sync core data via icloud or dropbox without a server
- peer-to-peer core data synchronization
- keep local sqlite database in sync across apple devices
When to choose
- you have a legacy Objective-C Core Data app needing device-to-device sync
- you want local-first sync with no server infrastructure
- you sync via file-based backends like iCloud or Dropbox
When to avoid
- starting a new Swift project - use Ensembles 3 instead
- you need SwiftData support
- you need end-to-end encryption or modern backends like S3 or WebDAV
