Does this skill promote performance optimizations?

Absolutely. It identifies where individual save operations should be replaced with 'CKModifyRecordsOperation' for more efficient batch processing.

Can it help with CloudKit error handling?

Yes, it specifically checks if your code respects 'retryAfterSeconds' and correctly parses 'CKErrorPartialFailure' for individual record errors.

Is it compatible with both Swift and Objective-C?

Yes, it is designed to recognize CloudKit patterns and API usage across all Apple ecosystem languages.

What CloudKit components does this skill review?

The skill analyzes CKContainer, CKDatabase, CKRecord, CKSubscription, CKShare, and CKZone implementations for best practices and common errors.

Why does it check for custom zones?

Custom zones are required for advanced features like CKShare and atomic transactions; the skill ensures you aren't over-relying on the default zone for production data.

Mobile Development

Reviews Apple CloudKit implementations to ensure proper container setup, error handling, and data synchronization patterns.

关于

This skill provides specialized auditing for Apple CloudKit integrations, ensuring developers follow best practices for CKContainer initialization, custom zone usage, and complex sharing patterns. It enforces robust error handling—specifically looking for retryAfterSeconds logic and CKErrorPartialFailure parsing—to prevent silent data loss. By validating batch operations and conflict resolution strategies, it helps developers build scalable, production-ready iCloud sync workflows that meet Apple's App Store standards.

主要功能

Verification of CloudKit error handling and backoff retry logic
Automated validation of CKContainer and database environment setup
Analysis of CKShare patterns and custom zone requirements for collaboration
Detailed auditing of CKRecord CRUD operations and batch processing logic
14 GitHub stars
Review of push notification subscriptions and silent sync triggers

使用场景

Troubleshooting data persistence issues and sync conflict resolution
Refactoring legacy CloudKit code to implement modern batch operations
Pre-deployment audits of iCloud sync logic before App Store submission
