App Security

Guidance for hardening Apple platform apps against common threats.

Keychain

Use the Keychain Services API to store secrets securely. Never store passwords in UserDefaults or plain files.

Storing Credentials

let query: [String: Any] = [
  kSecClass as String: kSecClassGenericPassword,
  kSecAttrAccount as String: account,
  kSecValueData as String: password.data(using: .utf8)!
]
SecItemAdd(query as CFDictionary, nil)

Keychain Access Groups

Share Keychain items across apps in the same team using access groups.

Certificate Pinning

Pin your server's certificate or public key to prevent MITM attacks.

Biometric Authentication

Use LocalAuthentication to gate sensitive flows behind Face ID or Touch ID.
