coredata-sync

What problem does it solve?

Core Data and CloudKit synchronization issues can cause data inconsistencies and race conditions between local and remote stores, especially during concurrent edits or offline periods.

Core Features & Use Cases

• Core Data + CloudKit integration patterns to stabilize sync, manage merge policies, and reduce stale reads.
• Race condition mitigation by deferring reads during mutations and using appropriate completion handling or async/await.
• Use Case: When an app edits data offline and then syncs across devices, this pattern helps maintain a consistent view.

Quick Start

Run a safe CloudKit sync pattern for Core Data by configuring NSPersistentCloudKitContainer and a merge policy in your app startup.
