What iOS versions does this skill support?

The skill is optimized for modern development, specifically targeting iOS 18 compatibility and the latest Swift concurrency patterns.

How does it ensure the app is bug-free?

It follows a 'Prove, Don't Promise' protocol where every change is automatically built and tested in a simulator environment before being reported as complete.

Can this skill build apps without opening the Xcode IDE?

This skill transforms Claude into a professional iOS developer capable of managing the full application lifecycle—from initial scaffolding to App Store submission—without requiring the user to write or read code. It operates on a 'Prove, Don't Promise' philosophy, utilizing CLI tools like xcodebuild and simctl to verify every implementation detail through automated tests and simulator deployments. By prioritizing small, verified steps and outcome-based reporting, it allows product owners to build high-quality, performant iPhone apps by describing requirements rather than managing source files.
