audit-swiftui-state-observation

Run the skill's shared lint runner against your SwiftUI sources, then read each located file in full to classify the model kind before reporting. The skill checks twelve defect rules covering ownership wrappers, world mixing, @Bindable projection, and environment injection.

@State owns a modern @Observable model created by the view, while @StateObject is the legacy owner for ObservableObject classes. Using @StateObject on a plain @Observable compiles but is a migration smell; on a struct it is a hard compile error.

No, the audit is macOS-only and SwiftUI-only. Its rules, availability floors such as macOS 14 for @Observable and macOS 26 for Observations, and its multi-window scene-level injection guidance are specific to macOS apps.

@ObservedObject does not own its object, so an initializer on it recreates the model on every parent re-render, silently resetting state when the model is a real ObservableObject. If the model is @Observable, the same code typically fails to compile because @Observable does not conform to ObservableObject.

Only two mechanical fixes are applied automatically: dropping redundant ObservableObject conformance and removing @Published inside an @Observable class. All other findings are flag-only because wrapper swaps depend on ownership intent a human must confirm.

The grep and ast-grep rules only locate candidates and cannot judge model kind, ownership, or cross-scope @Bindable re-wraps. Every hit must be read in full by the agent, and findings are reported only at 100 percent certainty.
