SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

SwiftData provides native persistence for SwiftUI apps using @Model and declarative queries, simplifying data modeling and UI synchronization.

Core Features & Use Cases

Declarative data models with @Model, @Attribute, and @Query for reactive UI updates
Relationship management and CloudKit integration with iOS 26+ features
Safe, concurrency-friendly data access using Swift 6 and @MainActor

Quick Start

Define your first @Model and run a sample @Query to see live UI updates.

FAQPage Schema

How do I implement SwiftData persistence in a SwiftUI app?▼

To implement SwiftData persistence in SwiftUI, use @Model to define typed data schemas and @Query to fetch data declaratively for reactive UI updates. This enables native offline storage and automatic view synchronization.

Does SwiftData work with CloudKit for iOS 26+ synchronization?▼

Yes, SwiftData works with CloudKit for iOS 26+ synchronization across Apple ecosystems. You must apply CloudKit constraints, ensuring model properties are either optional or have default values for safe bidirectional relationship syncing.

How do I manage Swift 6 concurrency with SwiftData?▼

You manage Swift 6 concurrency with SwiftData by applying @MainActor to ensure UI safety during data access. This enforces safe, concurrency-friendly data operations when performing CRUD actions and declarative queries.

What is the best way to handle bidirectional relationships in SwiftData?▼

The best way to handle bidirectional relationships in SwiftData is using the @Relationship macro within your @Model definitions. This ensures proper connection management between typed models during reactive UI updates and CloudKit synchronization.

Do I need to provide default values for SwiftData model properties?▼

Yes, you need to provide default values or make properties optional when using SwiftData with CloudKit. These CloudKit constraints are required to support safe synchronization and bidirectional relationships across Apple ecosystems.

Can I run live queries to update SwiftUI views with SwiftData?▼

Yes, you can run live queries to update SwiftUI views by using the @Query macro with your @Model definitions. This provides declarative data fetching that triggers reactive UI updates whenever the underlying persistence layer changes.
