What problem does it solve?

SwiftUI view files can become bloated, tangled, and hard to reason about when logic, side effects, and large inline layouts are mixed together, leading to unstable view structure and inconsistent state/data flow.

Core Features & Use Cases

  • Extract dedicated SwiftUI subviews to replace large computed some View helpers and keep each view section explicit, testable, and previewable.
  • Keep MV-first data flow (prefer MV over MVVM) by using @State, @Environment, and SwiftUI lifecycle modifiers instead of introducing view models by default.
  • Remove inline actions and side effects from body by moving real behavior into small methods and delegating business logic to services/models.
  • Preserve stable view identity by avoiding top-level conditional root branching and pushing conditions into localized modifiers/sections.
  • Standardize Observation usage to ensure @Observable reference models are stored and passed in the recommended way.

Quick Start

Ask the AI to refactor the provided SwiftUI view file to follow the guide by extracting subviews, moving side effects out of body, keeping MV-first state and dependencies, and ensuring a stable view tree.

FAQPage Schema
How do I refactor a large SwiftUI view into smaller subviews?

To refactor a large SwiftUI view, extract dedicated subviews to replace computed `some View` helpers, moving inline layouts into explicit, testable, and previewable sections while preserving a stable view tree.

What is the best way to remove side effects from a SwiftUI body?

Remove inline actions and side effects from the SwiftUI `body` by moving real behavior into small methods and delegating business logic to services or models. This keeps the view body purely declarative and predictable.

Should I use MVVM or MV-first patterns for SwiftUI state management?

SwiftUI state management should prefer MV-first patterns over MVVM by default, using `@State`, `@Environment`, and SwiftUI lifecycle modifiers instead of introducing view models, ensuring cleaner data flow and maintainability.

How do I standardize `@Observable` handling in modern SwiftUI?

Standardize `@Observable` handling by ensuring reference models are stored and passed using the recommended modern SwiftUI conventions. Correct `@Observable` usage guarantees consistent state propagation and data flow throughout the view tree.

Why does my SwiftUI view tree rebuild unexpectedly and how do I fix it?

An unstable SwiftUI view tree is often caused by top-level conditional root branching. Fix it by preserving stable view identity—push conditions into localized modifiers or sections rather than branching the root view.

Can I refactor SwiftUI views without introducing view models?

Yes, you can refactor SwiftUI views without view models by keeping MV-first data flow. Use `@State`, `@Environment`, and explicit dependency injection instead of defaulting to MVVM patterns for every extracted subview.
