FAQPage Schema
How do I migrate my app from Realm to SwiftData?▼

Migrating from Realm to SwiftData involves converting data models, changing threading models, and configuring CloudKit sync, using direct conversion for simple schemas or a transformation layer for complex ones.

What is the best way to handle threading model changes when moving from Realm to SwiftData?▼

Handling threading model changes requires converting Realm's thread-confined objects to SwiftData's MainActor-bound models, ensuring safe concurrency access during the schema transition process.

Can I transition Realm CloudKit sync to SwiftData directly?▼

Transitioning CloudKit sync involves configuring SwiftData's CloudKit integration, monitoring data across devices, and verifying workflows to replace Realm's deprecated synchronization paths.

How do you migrate complex Realm schemas to SwiftData?▼

Complex Realm schemas migrate to SwiftData using a transformation layer, phased rollouts, and testing with rollback planning to ensure robust data integrity during the transition.

Does migrating from Realm to SwiftData require a phased rollout?▼

A phased rollout is recommended for complex Realm to SwiftData migrations to implement testing, verification, and rollback planning, ensuring production stability during data conversion.
