Maksim Dimitrov 6792e91735 feat: add Swift language-specific rules
Add 5 rule files for Swift following the established pattern used by
TypeScript, Python, and Go rule sets. Covers Swift 6 strict concurrency,
Swift Testing framework, protocol-oriented patterns, Keychain-based
secret management, and SwiftFormat/SwiftLint hooks.

Swift Security

This file extends common/security.md with Swift specific content.

Secret Management

  • Use Keychain Services for sensitive data (tokens, passwords, keys) — never UserDefaults
  • Use environment variables or .xcconfig files for build-time secrets
  • Never hardcode secrets in source — decompilation tools extract them trivially
let apiKey = ProcessInfo.processInfo.environment["API_KEY"]
guard let apiKey, !apiKey.isEmpty else {
    fatalError("API_KEY not configured")
}

Transport Security

  • App Transport Security (ATS) is enforced by default — do not disable it
  • Use certificate pinning for critical endpoints
  • Validate all server certificates

Input Validation

  • Sanitize all user input before display to prevent injection
  • Use URL(string:) with validation rather than force-unwrapping
  • Validate data from external sources (APIs, deep links, pasteboard) before processing
