SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires PyYAML, and includes scripts (resource) and references (resource) components.

What problem does it solve?

Provide a docs-first workflow to decide where responsibilities belong in a SwiftUI app and which data-flow mechanisms to use so app structure remains maintainable and platform-correct. It helps teams and maintainers correct wrapper-heavy designs, eliminate state scattering, and avoid environment- or preference-key abuse that obscures ownership.

Core Features & Use Cases

  • Ownership Boundary Selection: Recommend whether a responsibility belongs at the App, Scene, focused-scene, view-tree, or local-view boundary.
  • Transport Recommendation: Choose between explicit initializer injection, Binding, environment values, FocusState, focused values/objects, focused scene values/objects, preference keys, or local state.
  • Anti-Pattern Detection and Corrections: Detect environment dumping grounds, giant root views, wrapper-heavy layers, hidden modifier control flow, and preference-keys-as-state-bus; propose corrective refactors.
  • Commands, Focus, and Scene Coordination: Advise on command ownership, focused-context publication, and native scene actions for settings and windows.
  • Use Case: Refactor a single giant App root view into scene-local state, move inspector state into a UtilityWindow, or choose focused-scene publication for command-sensitive editor context.

Quick Start

Help me decide app versus scene ownership and the appropriate data-flow transport for a SwiftUI app with multiple windows, commands, and focused editors.

Frequently Asked Questions about swiftui-app-architecture-workflow

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I decide between App, Scene, and view-level ownership boundaries in SwiftUI?▼

SwiftUI ownership boundaries are decided by identifying whether a responsibility belongs at the App, Scene, focused-scene, view-tree, or local-view level to maintain correct app structure. This approach selects the correct boundary for state and data-flow transport.

What is the best way to choose data-flow transport mechanisms in SwiftUI?▼

Choosing SwiftUI data-flow transport requires selecting between initializer injection, Binding, environment values, FocusState, focused values, or preference keys based on the identified ownership boundary. Explicit transport selection prevents state scattering and wrapper-heavy designs.

Why does my SwiftUI app have environment dumping grounds and preference-key abuse?▼

Environment dumping grounds and preference-key abuse occur when SwiftUI state responsibilities bypass explicit ownership boundaries. Correcting these anti-patterns requires refactoring to explicit initializer injection or scene-local state instead of using environment or preference keys as a state bus.

Can I coordinate command menus and focus contexts across multiple SwiftUI windows?▼

Command menus and focus contexts coordinate across SwiftUI windows by publishing focused values, focused scene values, and objects within the Scene and WindowGroup structure. This ensures command ownership maps correctly to the active focused editor context.

How do I refactor a giant SwiftUI root view into scene-local state?▼

Refactoring a giant SwiftUI root view into scene-local state involves moving responsibilities down to the Scene or focused-scene boundary and selecting appropriate data-flow transport. This eliminates root view bloat and clarifies ownership within the app structure.

Does this SwiftUI architecture workflow apply to DocumentGroup and Settings scenes?▼

This SwiftUI architecture workflow applies to App, Scene, WindowGroup, Window, Settings, and DocumentGroup structures across Apple platforms. It provides ownership boundary decisions and transport recommendations for all native scene types.
