System Documentation

What problem does it solve?

This skill helps iOS developers decide between SwiftData and CoreData for data persistence, and manage migrations and performance considerations.

Core Features & Use Cases

  • Framework selection guidance: When to use SwiftData vs CoreData based on deployment target, app complexity, and sync requirements.
  • Migration strategy: How to version schemas, plan migrations, and avoid breaking changes with iCloud or external migrations.
  • Performance patterns: Guidance on fetch batching, blob handling, and relationship faulting during data access.
  • Use Case: You are starting a new iOS app with SwiftUI and want a simple data layer; or you are migrating a CoreData app to SwiftData with minimal disruption.

Quick Start

Use the skill to evaluate a new iOS project for persistence: choose between SwiftData or CoreData and outline a migration plan.
