Valet is a Swift library that simplifies secure data storage in the Apple Keychain across iOS, tvOS, watchOS, and macOS.
The Keychain is Apple's system for storing sensitive information like passwords and cryptographic keys, but its API is notoriously complex and error-prone. Valet abstracts away that complexity by providing a straightforward interface for storing and retrieving data securely. Developers can work with the Keychain without needing to understand its underlying mechanics, reducing the surface area for security mistakes.
Valet suits any Apple platform project that needs to persist sensitive data locally. It handles the Keychain's quirks and configuration details internally, making it appropriate for developers who want security best practices without the learning curve. The library supports biometric authentication through Face ID and Touch ID integration, allowing apps to gate access to stored secrets behind user authentication.
The project maintains a steady cadence of updates and remains responsive to issues and pull requests. Development activity shows consistent engagement with the codebase, suggesting the maintainers actively monitor the library's health and compatibility with new Apple platform releases.
