The Agent Skills Directory

[SAFE]: The skill serves as a technical reference for Swift and iOS development, covering SPM project structures, modern concurrency (async/await, actors), and framework patterns for SwiftUI, Combine, and Vapor. All provided code snippets are standard implementations. External references, such as the apple/swift-algorithms package, target trusted organizations. The skill includes a dedicated anti-patterns section that explicitly warns against insecure practices like storing secrets in UserDefaults and recommends using the iOS Keychain API instead.
