Hi everyone! I'd like to share two MIT-licensed packages, built in Swift 6 language mode with no dependencies.
DesignSystemKit: semantic tokens, a typography scale and SwiftUI + UIKit components. Themes can be switched at runtime for white-label and multi-tenant apps, and are checked for WCAG contrast. Also includes Dynamic Type and localized strings.
SecureStorageKit: an async/await Keychain wrapper with item-level biometric access control, AES-256-GCM encryption in a versioned format with key rotation, Secure Enclave signing, a token store with single-flight refresh, and encrypted backups. Docs/ThreatModel.md describes exactly what is and isn't protected. It hasn't been independently audited yet, so I'd especially value reviews of the crypto and Keychain code.
Feedback on API design is very welcome!
