This one gives Claude deep knowledge of Swift 6, SwiftUI, and the modern Apple development stack. It's built for native iOS, macOS, and visionOS work, covering everything from SwiftData and structured concurrency with Actors to performance optimization with Instruments. The skill handles migrations from UIKit and Objective-C, integrates system frameworks like HealthKit and WidgetKit, and even covers server-side Swift with Vapor. With 134 installs and passing security audits, it's a solid choice if you're shipping apps across the Apple ecosystem and want Claude to understand modern patterns instead of outdated tutorials.
