# CloudKit Sync Generator Generate production-ready CloudKit sync infrastructure using `CKSyncEngine` (iOS 17+ / macOS 14+), the modern replacement for manual `CKOperation` chains. ## When This Skill Activates Use this skill when the user: - Asks to "add iCloud sync" or "sync data across devices" - Mentions "CloudKit", "CKSyncEngine", or "cloud sync" - Wants to "share data between users" via iCloud - Asks about "conflict resolution" for synced data - Mentions "CKRecord", "CKShare", or "CKRecordZone" ## Pre-Generation Checks ### 1. Project Context Detection Before generating, ALWAYS check: ```bash # Check deployment target (CKSyncEngine requires iOS 17+ / macOS 14+) grep -r "platform" Package.swift 2>/dev/null || true grep -r "IPHONEOS_DEPLOYMENT_TARGET\|MACOSX_DEPLOYMENT_TARGET" --include="*.pbxproj" | head -3 # Find existing CloudKit implementations rg -l "CKSyncEngine\|CKContainer\|CKRecord\|CKOperation" --type swift | head -10 # Check for existing entitlements find . -name "*.entitlements" -exec cat {} \; 2>/dev/null | grep -i "icloud" # Check existing persistence layer rg -l "@Model\|NSManagedObject\|PersistentModel" --type swift | head -5 # Check for existing sync infrastructure rg "CKSyncEngineDelegate\|CKSubscription\|CKFetchRecordZoneChanges" --type swift | head -5 ``` ### 2. Compatibility Verification **CKSyncEngine requires:** - iOS 17.0+ / macOS 14.0+ / watchOS 10.0+ / tvOS 17.0+ - CloudKit entitlement - Active iCloud account on device If deployment t...
