How does this skill help with iOS Keychain management?

It provides a standardized Swift class to handle saving, loading, and deleting sensitive data with appropriate accessibility levels such as kSecAttrAccessibleAfterFirstUnlock.

What level of data protection does it offer for local files?

It implements iOS Data Protection attributes, allowing you to specify encryption levels that ensure files are inaccessible when the device is locked.

Is this skill suitable for enterprise-grade applications?

Absolutely; it follows enterprise development patterns for secure coding and data privacy required by high-compliance industries.

Can I use this for API key protection?

The skill demonstrates how to use .xcconfig files and basic obfuscation to avoid hardcoding secrets directly into your source code.

Does it support SSL pinning for network requests?

Yes, it includes a PinnedURLSessionDelegate pattern to validate server certificates against local copies, effectively preventing MITM attacks.
