SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Implementing robust, App Store-compliant security features for macOS apps requires navigating complex Apple security frameworks, avoiding common misconfigurations, and adhering to the latest platform requirements for macOS 26+. This Skill eliminates the guesswork by providing production-ready guidance for all core macOS security workflows.

Core Features & Use Cases

  • Keychain & Secure Storage: Securely store credentials and sensitive data, with support for app group sharing between apps and privileged helper tools.
  • Biometric & Authentication: Implement Touch ID, Apple Watch unlock, passkey, and Sign in with Apple flows with proper error handling and fallback logic.
  • Cryptography & Secure Enclave: Use CryptoKit for symmetric/asymmetric encryption, post-quantum primitives, and SecureEnclave-backed key operations for hardware-level security.
  • Compliance & Hardening: Configure Hardened Runtime entitlements and App Sandbox to meet Mac App Store notarization requirements.
  • Use Case: For example, use this Skill to add Touch ID-gated keychain storage for user API tokens, or implement post-quantum encrypted data sync for a cross-platform productivity app.

Quick Start

Use the swift-security-macos skill to implement Touch ID-protected keychain storage for user credentials in your macOS app, following Apple's latest security best practices for macOS 26+.

Frequently Asked Questions about swift-security-macos

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement Touch ID authentication for keychain storage in a macOS app?▼

To implement Touch ID authentication for keychain storage, you configure biometric access requests that gate the retrieval of stored credentials. This requires proper error handling and fallback logic to manage cases where biometric validation is unavailable.

What is the best way to configure Hardened Runtime and App Sandbox for Mac App Store notarization?▼

Configuring Hardened Runtime and App Sandbox for notarization involves setting specific entitlements to meet Apple's distribution rules. This ensures your macOS 26+ application satisfies Mac App Store compliance and protects sensitive data.

How does Secure Enclave key management work with CryptoKit in Swift?▼

Secure Enclave key management with CryptoKit delegates cryptographic operations to dedicated hardware. This provides hardware-level security for symmetric and asymmetric encryption, including post-quantum primitives, without exposing raw key material.

Can I share keychain items between macOS apps and privileged helper tools?▼

You can share keychain items between macOS apps and privileged helper tools using app group sharing. This allows multiple components to securely access the same stored credentials and sensitive data across your application ecosystem.

How do I set up passkeys and Sign in with Apple flows for macOS?▼

Setting up passkeys and Sign in with Apple flows requires integrating Apple's modern authentication frameworks within your Swift application. This provides passwordless authentication with proper fallback logic for user convenience.

When do I need post-quantum cryptography in my macOS application?▼

You need post-quantum cryptography in your macOS application when preparing for future threats. CryptoKit provides post-quantum primitives to ensure encrypted data sync remains secure against emerging computational capabilities.
