Publish window state from a view using .focusedSceneValue, then read it in your Commands struct with @FocusedValue or @FocusedBinding. Commands are scene-level and cannot access a window's @State directly, so this focus-based routing is required.

Sign all components inside-out with codesign using a Developer ID identity, hardened runtime, and secure timestamp, then submit with xcrun notarytool and staple the ticket with xcrun stapler. The older altool is no longer accepted by Apple's notary service.

Xcode debug builds do not enable the App Sandbox by default, so file and network operations succeed during development but are denied in sandboxed release builds. Enable the App Sandbox capability in debug or test release and TestFlight builds.

Use NSViewRepresentable when SwiftUI is the host and you need to embed an AppKit view inside it. Use NSHostingController or NSHostingView when AppKit is the host and you need SwiftUI content in split views, sheets, popovers, or collection cells.

Create a security-scoped bookmark with bookmarkData(options: .withSecurityScope) when the user picks the file, store the data in a file in your container, then resolve it later and call startAccessingSecurityScopedResource. Always balance access with stopAccessingSecurityScopedResource.

No. The --deep flag applies identical entitlements and options to every nested component, which breaks components needing different entitlements such as XPC services. Sign each component individually from the innermost framework outward to the main app bundle.
