Mirror an iOS Simulator into the Codex in-app browser and render SwiftUI previews from importable Swift packages in that simulator with hot reload. Use when a user wants to watch or interact with an iOS app in the browser, see a SwiftUI preview outside Xcode Canvas, iterate live on a preview, or capture browser-visible simulator proof.

Doc Screenshots

by WordPress

Annotate UI screenshots with documentation callouts in Fellyph's established visual style — uniform-width orange arrows with white halos, double-stroke target outlines, numbered callout cards, dim overlays and a framed canvas. Use this whenever the user asks to annotate a screenshot, add arrows or callouts to a screenshot, create documentation images, highlight UI controls in a capture, or produce docs/tutorial visuals for Playground, Studio or any web UI — even if they just say "add arrows to this" or "make a docs screenshot".
