The KeychainTouchID sample shows how to store Touch ID protected items to the keychain and how to query for those items with custom message prompts. You’ll see how to use the keychain item accessibility class, which invalidates items when the passcode is removed. You’ll also find out how to use the LocalAuthentication class to invoke Touch ID verification without involving the keychain.
