Review Checklist

  • Account status checked before private/shared database operations
  • Custom zones used (not default zone) for production data
  • All CloudKit errors handled with retryAfterSeconds respected
  • serverRecordChanged conflicts handled with proper merge logic
  • CKErrorPartialFailure parsed for individual record errors
  • Batch operations used (CKModifyRecordsOperation) not individual saves
  • Large binary data stored as CKAsset (records have 1MB limit)
  • Record keys type-safe (enums) not string literals
  • UI updates dispatched to main thread from callbacks
  • CKAccountChangedNotification observed for account switches
  • Subscriptions have unique IDs to prevent duplicates
  • CKShare uses custom zone (sharing requires custom zones)

When to Load References

  • Reviewing container/database setup or zones -> container-setup.md
  • Reviewing record CRUD or relationships -> records.md
  • Reviewing push notifications or sync triggers -> subscriptions.md
  • Reviewing sharing or collaboration features -> sharing.md

Review Questions

  1. What happens when the user is signed out of iCloud?
  2. Does error handling respect rate limiting (retryAfterSeconds)?
  3. Are conflicts resolved or does data get overwritten silently?
  4. Is the schema deployed to production before App Store release?
  5. Are shared records in custom zones (required for CKShare)?
