tl;dr: Once Xcode is installed and configured (Apple ID signed in, Developer ID cert created, notarytool credentials stored), you can ship Mac and iOS apps entirely from the command line using xcodebuild, notarytool, stapler, devicectl, and XcodeGen—no GUI required. The author's setup consists of a `release.sh` script that handles the archive → sign → notarize → staple → install pipeline, plus a `CLAUDE.md` file that tells Claude Code how to use it. This lets an LLM agent handle the entire build/ship workflow without ever opening Xcode.
