How does the 'Prove, Don't Promise' principle work?

Claude runs automated builds and unit tests after every single code change to provide tangible proof that the update works, rather than just stating that the code should work.

Do I need to have Xcode installed to use this skill?

Yes, you need the Xcode Command Line Tools and SDKs installed on your system, but this skill operates entirely through the terminal without requiring you to open the Xcode GUI.

Is this skill limited to SwiftUI apps?

No, it supports SwiftUI, AppKit, and various system APIs, covering everything from menu bar utilities to complex document-based applications.

Can this skill help with App Store submission?

Yes, it includes specialized workflows for code signing, notarizing, and preparing your application for distribution or App Store release.

Mobile Development

Builds professional native macOS applications using Swift, SwiftUI, and AppKit through a CLI-only workflow.

About

This skill transforms Claude into a specialized macOS developer capable of managing the entire application lifecycle—from initial scaffolding to App Store submission—entirely via the command line. It emphasizes a strict 'prove, don't promise' approach, where every code change is automatically verified through builds and tests to ensure the application remains in a working state. It is ideal for users who want to act as product owners, providing requirements while Claude handles the technical implementation, debugging, performance optimization, and notarization without requiring the Xcode GUI.
