💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides comprehensive guidance on using SwiftData for data modeling, persistence, state management, and synchronization in modular MVVM-C applications, ensuring data integrity and efficient app architecture.

Core Features & Use Cases

  • Data Modeling: Best practices for defining @Model entities and mapping them to domain structs.
  • Persistence Setup: Correct configuration of ModelContainer and ModelContext for reliable data storage.
  • CRUD Operations: Implementing efficient insert, update, and delete patterns.
  • Sync & Networking: Strategies for offline-first data synchronization and API integration.
  • Schema Management: Planning and executing schema migrations safely.
  • Use Case: Building a complex iOS application that requires robust local data storage, offline capabilities, and seamless synchronization with a backend API, while adhering to a clean, modular architecture.

Quick Start

FAQPage Schema
How do I set up SwiftData persistence in a modular MVVM-C iOS app?▼

Set up SwiftData persistence by correctly configuring the ModelContainer and ModelContext for reliable local storage. This approach ensures data integrity and efficient app architecture within modular MVVM-C boundaries.

What is the best way to map SwiftData @Model entities to domain structs?▼

The best way to map @Model entities is to follow SwiftData best practices for data modeling, defining entity classes and mapping them directly to domain structs. This maintains clean data-only boundaries in your application.

How does SwiftData handle offline-first data synchronization and API integration?▼

SwiftData handles offline-first data synchronization using stale-while-revalidate reads and optimistic queued writes. These strategies manage API integration efficiently, ensuring data syncs reliably when network connectivity is restored.

Can I use SwiftData with SwiftUI while keeping data logic in separate boundaries?▼

Yes, you can use SwiftData with SwiftUI while maintaining Data-only boundaries. The Skill provides best practices for integrating persistence and state management cleanly within your SwiftUI views.

How do I execute schema migrations safely when using SwiftData?▼

Execute schema migrations safely by planning and executing schema management strategies provided by the Skill. This ensures data integrity is maintained across app updates without losing local data.
