audit-swiftui-appkit-interop

Run the shared lint runner with the audit-swiftui-appkit-interop skill against your source directory to locate candidates via grep and ast-grep rules. Then read each flagged file in full, confirm defects at 100% certainty, and write findings to the swiftui-audits/appkit-interop folder.

It detects ten defect classes: missing updateNSView, missing makeCoordinator with a Binding, first-responder misuse, controllers flattened to bare views, missing NSHostingController hosting, Sendable closure races, in-window material faking vibrancy, unbridged scene chrome, missing dismantleNSView cleanup, and ungated newer bridge APIs.

No, every finding uses flag-only mode because bridge fixes require human context. The audit reports each defect with the canonical correct shape backed by a real permalinked example from shipping macOS apps, and the developer applies the fix.

The representable likely lacks updateNSView, which SwiftUI calls on every state change while makeNSView runs only once. Implement updateNSView with a guarded write, such as checking the value differs before assigning, so state changes propagate without resetting the cursor.

Toolbar and navigationTitle bridge on macOS 14+ via sceneBridgingOptions when the hosting view is the window contentView. The searchable modifier has no scene bridge and never renders under a bare NSWindow with NSHostingView on any macOS version.

It fires under the Swift 6 language mode when a Sendable closure reads main-actor state at the Coordinator boundary and default Main Actor isolation is off. The audit reads SWIFT_STRICT_CONCURRENCY and isolation build settings before flagging this defect.
