Apple ships seven bundled agent skills in Xcode 27

Export Apple-authored skill packs for SwiftUI, UIKit, testing, and security via `xcrun agent skills export` — read them as guidance or feed them to agents in your toolchain.

Summary

Coding agents struggle with brand-new APIs, deprecated patterns, and platform footguns. These skills embed Apple's own framework guidance directly in Xcode, replacing reliance on community documentation for cutting-edge patterns and reducing context cost for agent reasoning.

Why it matters

Implementation verdict

Ready now. Single command pulls seven Markdown folders containing Apple's recommendations for modern Swift/SwiftUI practice, UIKit migration, test modernization, security auditing, C bounds safety, and device interaction. Requires Xcode 27 with command line tools pointed at the new toolchain. Use immediately as reference docs or inject into agents outside Xcode.
