Run just run for the iPhone simulator, or just run-mac for Mac Catalyst. just build-mac builds without launching the Mac app. Both regenerate the Xcode project from project.yml. The Mac recipes use ad-hoc signing for local development; release/archive signing settings are unchanged.

Quick Question on macOS

While the Catalyst app is running, Option+Space toggles a floating Quick Question panel, including over other applications. The prompt is focused as soon as it opens, with any existing prompt selected so typing replaces it. The same select-on-open behavior applies to Quick Question on iPhone and iPad. Return submits; Shift+Return inserts a new line. Escape, a second Option+Space, the close button, or clicking outside dismisses it. Hiding the panel preserves the draft and answer and lets an in-flight answer finish. Open in Chat saves the question and answer in the regular workspace.

The regular Mac chat/search composer uses the same Return/Shift+Return rules. Holding Return does not repeatedly submit. The iOS software keyboard is unchanged.

Closing the last Mac window leaves Sybil running, so Option+Space still works. Use Sybil → Quit Sybil or Command+Q to quit the application. The Catalyst build opts out of automatic termination, and the native shortcut service holds a matching automatic-termination activity until it stops. No hidden keep-alive window or sleep-preventing activity is used. Mac scene support also allows the workspace to reopen after its last window is closed.

When Catalyst is backgrounded, opening Quick Question first requests app activation and waits for UIKit to enter the foreground before creating or ordering the native panel. Presentation is deferred out of the hotkey event callback. Pressing Option+Space again cancels a pending presentation. Dismissing a panel that required activation returns focus to the previous app; explicitly opening the workspace keeps focus in Sybil.

On Mac, Command+N starts a new chat in the focused workspace, or opens a new workspace window when none are open. Command+Shift+N always opens a new window, including while signed out. Command+Option+N starts a new search; iOS retains its existing Command+Shift+N search shortcut.

The shortcut is also shown under File → Quick Question. If another application already owns Option+Space, the panel reports that the shortcut is unavailable; the menu item can still be clicked. No Accessibility or Input Monitoring grant is needed for the registered hotkey.

The native AppKit panel and Carbon hotkey live in Apps/SybilMacQuickQuestion, a macOS bundle embedded only for the Mac Catalyst destination. Catalyst loads it through the Foundation-only SybilMacQuickQuestionBridge contract. Requests, provider/model preferences, streaming, and conversion to chat remain in the existing SybilViewModel; there is no separate backend or API contract. The panel uses AppKit controls rather than trying to load the macOS SwiftUI runtime into a Catalyst process.

The iPhone/iPad app keeps its existing Quick Question sheet and Home Screen quick action, and does not build or embed the macOS helper.

Verification

just test: existing Swift package tests on the iPhone simulator.
From Packages/Sybil, run xcodebuild test -scheme Sybil -destination 'platform=macOS,variant=Mac Catalyst' -parallel-testing-enabled NO for package tests including the Catalyst panel controller.
For a manual Mac check, open the panel from another app, type immediately, submit, hide/reopen during streaming, and verify Escape/outside-click dismissal returns input to the previous app. Check a second display and a full-screen Space when available.
Close every Mac window, invoke Option+Space, and verify the saved question and answer remain available. Reopen the workspace from the panel, then explicitly quit with Command+Q. Rebuild and relaunch after changing lifecycle plist keys.
In both Mac and iOS Quick Question, reopen an existing prompt and type to replace it. In the Mac workspace, verify Return submits and Shift+Return adds a newline.
Check Command+N both with a workspace open and after closing every workspace. Command+Shift+N must open another window even when one already exists, and Command+Option+N must start a search without opening a window.
With all workspace windows closed, switch to another app and repeatedly open and dismiss Quick Question, including two quick Option+Space presses while it is opening. Check that no late panel appears after cancellation and that no UINSAppLifecycleStateRunningNoOpenWindows assertion occurs.
