What problem does it solve?

SwiftUI projects often accumulate tangled state, deep view hierarchies, and ad-hoc navigation that hinder maintainability and testability. This guide codifies best practices to keep state predictable, promote small reusable views, and establish robust navigation patterns.

Core Features & Use Cases

• Stateless views by default; place business logic in a ViewModel or model layer and bind to simple state.
• Favor small, composable view components; extract large bodies into private nested views for readability.
• Use stable identities in lists and typed navigation; avoid using indices or string-based routes.
• Prefer NavigationStack (and NavigationSplitView on supported platforms) for contemporary navigation and clear routing boundaries.
• Address performance and accessibility: keep body pure, provide meaningful labels, and design tappable areas with sufficient padding.

Quick Start

Refactor an existing SwiftUI screen to move business logic into a minimal ViewModel, extract large bodies into private subviews, and adopt a typed NavigationStack-based flow.
