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.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'ios-simulator-browser' ] || [ -L ~/.agents/skills/'ios-simulator-browser' ]; then echo 'A skill folder named ios-simulator-browser already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/openai/plugins' "$d" && git -C "$d" checkout --quiet 'd420d13051bffe4543ed39e30fa46b87148e47dd' -- 'plugins/build-ios-apps/skills/ios-simulator-browser' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/build-ios-apps/skills/ios-simulator-browser' ~/.agents/skills/'ios-simulator-browser' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'ios-simulator-browser' ~/.claude/skills/'ios-simulator-browser' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
