Sync

What is Sync?

Sync eases your everyday job of parsing a JSON response and syncing it with Core Data. Sync is a lightweight Swift library that uses a convention-over-configuration paradigm to facilitate your workflow.

Syncing JSON to Core Data is a repetitive tasks that often demands adding a lot of boilerplate code. Mapping attributes, mapping relationships, diffing for inserts, removals and updates are often tasks that don’t change between apps. Taking this in account we took the challenge to abstract this into a library. Sync uses the knowledge of your Core Data model to infer all the mapping between your JSON and Core Data, once you use it, it feels so obvious that you’ll wonder why you weren’t doing this before.

• Automatic mapping of camelCase or snake_case JSON into Core Data
• Thread-safe saving, we handle retrieving and storing objects in the right threads
• Diffing of changes, updated, inserted and deleted objects (which are automatically purged for you)
• Auto-mapping of relationships (one-to-one, one-to-many and many-to-many)
• Smart-updates, only updates your NSManagedObjects if the server values are different from your local ones
• Uniquing, one Core Data entry per primary key
• NSOperation subclass, any Sync process can be queued and cancelled at any time!
