ios-development skillA

ios-development is agent-read markdown (skill) from cowork-os/cowork-os: iOS/Swift development: SwiftUI, UIKit, Core Data, Xcode builds, simulator management, code signing, and App Store submission..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
