swiftdata-inheritance

What problem does it solve?

This Skill helps developers correctly implement and query class inheritance in SwiftData, avoiding common pitfalls and ensuring robust model design for hierarchical data.

Core Features & Use Cases

• Hierarchical Model Design: Guides on when to use class inheritance versus enums or protocols for SwiftData models.
• Querying Across Types: Demonstrates how to fetch data from base classes and filter for specific subclasses.
• API Patterns: Provides clear examples for base and subclass declarations, relationship handling, and ModelContainer setup.
• Use Case: When building a SwiftData app with different types of user-defined events (e.g., MeetingEvent, ReminderEvent, TaskEvent), this skill shows how to model them efficiently under a common CalendarEvent base class and query them effectively.

Quick Start

Use the swiftdata-inheritance skill to understand how to define and query subclasses in SwiftData.
