What encryption methods does this skill recommend?

The skill prioritizes Apple's CryptoKit for symmetric encryption (AES-GCM), hashing (SHA-256), and message authentication (HMAC).

Can it help implement biometric authentication?

Absolutely, it provides standardized patterns for LocalAuthentication (Face ID/Touch ID) and securing Keychain items with biometric requirements.

Does this skill support the latest Swift versions?

Yes, it is specifically designed for Swift 6.3 and modern Apple frameworks, including SwiftUI and the latest iOS 26+ features.

Does it help with App Store privacy requirements?

Yes, it includes guidance for auditing and configuring Privacy Manifests, which are now mandatory for many apps on the Apple App Store.

Why should I use Keychain instead of UserDefaults for secrets?

Keychain is hardware-encrypted and access-controlled by the system, whereas UserDefaults stores data in plain text, making it insecure for sensitive data like tokens or passwords.

Mobile Development

Implements industry-standard security features for iOS applications including Keychain management, hardware encryption, and biometric authentication.

This skill provides comprehensive guidance for securing modern iOS applications using Swift and SwiftUI. It enables Claude to implement secure data storage via Keychain Services, utilize hardware-backed encryption with CryptoKit and the Secure Enclave, and integrate biometric authentication like Face ID and Touch ID. By following Apple's best practices, it helps developers manage App Transport Security (ATS), perform certificate pinning, and audit privacy manifests to ensure user data remains protected and compliant with the latest App Store security guidelines.
