# Is SwiftData incompatible with MVVM? The standard answer betrays a deep misunderstanding of 3 key principles that drive SwiftUI’s architecture

**[Matteo Manferdini](https://daily.dev/sources/matteomanferdini)** · 13 min read · 1 upvotes · 0 comments

## Summary

Explores how to properly implement MVVM architecture with SwiftData in SwiftUI apps by debunking three common misconceptions: that @Query properties are sources of truth, that accessing the shared model context is unique to @Query, and that @Query properties are passively notified of changes. Demonstrates how to create view models that work seamlessly with SwiftData by leveraging the DynamicProperty protocol and implementing custom property wrappers, eliminating boilerplate code while maintaining testability and separation of concerns.
