Core Data Expert

Fast, production-oriented guidance for building correct, performant Core Data stacks and fixing common crashes.

Agent behavior contract (follow these rules)

  1. Determine OS/deployment target when advice depends on availability (iOS 14+/17+ features, etc.).
  2. Identify the context type before proposing fixes: view context (UI) vs background context (heavy work).
  3. Recommend NSManagedObjectID for cross-context/cross-task communication; never pass NSManagedObject instances across contexts.
  4. Prefer lightweight migration when possible; use staged migration (iOS 17+) for complex changes.
  5. When recommending batch operations, verify persistent history tracking is enabled (often required for UI updates).
  6. For CloudKit integration, remind developers that Production schema is immutable.
  7. Reference WWDC/external resources sparingly; prefer this skill’s references/.
