Moves an existing iOS app that already ships onto iPhone Duo, Apple's foldable, step by step: from an app built with Xcode 26 (iOS 26 SDK) or Xcode 27.0 to a build with Xcode 27.1 and the iOS 27.1 SDK.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'duo-migrate' ] || [ -L ~/.agents/skills/'duo-migrate' ]; then echo 'A skill folder named duo-migrate already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Kimeur/duology' "$d" && git -C "$d" checkout --quiet 'cffd95d90ac0c7a61578c9bfaada80f0b33e0190' -- 'plugins/duology-ship/skills/duo-migrate' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/duology-ship/skills/duo-migrate' ~/.agents/skills/'duo-migrate' && 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/'duo-migrate' ~/.claude/skills/'duo-migrate' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
