FAQPage Schema
How do I persist SwiftData models across app launches and restarts?▼

To persist SwiftData models across app launches, define @Model schemas and configure a ModelContainer with a SwiftData-backed store. This enables durable local storage that survives user sessions and app updates.

What's the best way to set up offline-first local storage with SwiftData?▼

Setting up offline-first local storage with SwiftData requires defining @Model schemas and configuring a swappable store architecture. This approach ensures consistent state restoration and durable data access after relaunch.

Can I use an in-memory store for testing and a SwiftData-backed store for production?▼

Yes, you can use an in-memory store for testing and a SwiftData-backed store for production. This Skill provides a swappable store architecture, allowing you to easily switch storage backends without changing domain models.

How do SwiftData @Model schemas and ModelContainer setup work together?▼

SwiftData @Model schemas define your data structures and relationships, while the ModelContainer setup manages the storage backend. Together, they enable model-driven persistence with durable, swappable storage for offline-first apps.

Does this approach support state restoration after an iOS app relaunch?▼

Yes, this approach supports state restoration after an iOS app relaunch. By using a SwiftData-backed store with defined @Model schemas, your app maintains consistent offline-first state restoration across user sessions.
