How can Objective C apps handle user authentication and secure user data?
Objective C apps can handle user authentication and secure user data by implementing various security measures. This includes using secure protocols like HTTPS for communication, hashing passwords to prevent them from being stored in plaintext, and implementing strong encryption algorithms for storing user data. Additionally, Objective C apps can utilize secure authentication methods such as OAuth or token-based authentication, which provide an extra layer of security. It is also important to regularly update the app and its dependencies to patch any security vulnerabilities. By following these best practices, Objective C apps can ensure the authentication and data security of their users.
