# iOS Simulator Browser ## Browser Workflow 1. Obtain an explicit Simulator UDID from the existing iOS build/run workflow or from `xcrun simctl list devices available`. 2. Start `serve-sim` in a long-running terminal pinned to that simulator. Clean up any tracked stale helper for this simulator before starting, and install a trap so the helper is cleaned up when this terminal exits: ```bash SIM="<simulator-udid>" cleanup_serve_sim() { npx --yes serve-sim@latest --kill "$SIM" >/dev/null 2>&1 || true } trap cleanup_serve_sim EXIT INT TERM HUP cleanup_serve_sim npx --yes serve-sim@latest "$SIM" ``` 3. Open the exact local preview URL printed by `serve-sim` in the Codex in-app browser. 4. Verify that a real frame is rendering before reporting success. A loaded page alone is not proof that the simulator stream is healthy. - Keep the terminal alive while the browser mirror is in use. When finished, stop the terminal and wait for it to exit so the trap runs. - If the terminal disappeared or did not exit cleanly, run `npx --yes serve-sim@latest --kill "$SIM"` before starting another mirror for that simulator. - Never run an unscoped `serve-sim --kill`; another thread may own a different simulator mirror. ## SwiftUI Preview Workflow Use the bundled launcher when the requested previews live in an importable Swift package. Point it at the package manifest and select the target whose previews should be displayed. It generates a disposable host project
