# Why Dismissing View Models in SwiftUI is Stifling your App’s Maintainability and Testability (And the Proven Principles for a Better Architecture)

**[Matteo Manferdini](https://daily.dev/sources/matteomanferdini)** · 27 min read · 0 upvotes · 0 comments

## Summary

Explores why view models remain essential in SwiftUI applications despite common arguments against them. Demonstrates how MVVM pattern improves testability, maintainability, and code reuse by separating business logic from views. Addresses misconceptions about Apple's stance on view models and shows how they work with frameworks like SwiftData. Provides practical implementation examples and argues against the MV pattern as overly restrictive.
