Have you had experience storing user information in previous projects?

Yes, in previous projects I have worked with storing user information. This typically included:

• Using UserDefaults for storing simple settings and small data.
• Saving user data in a local database, such as Core Data or Realm, for more complex structures.
• Working with Keychain for securely storing confidential information, such as authorization tokens.
• Synchronizing data with a server via API to ensure relevance and access from different devices.

Example of saving a simple value in UserDefaults:

UserDefaults.standard.set(true, forKey: "isUserLoggedIn")

This approach allows for saving the application's state and personalizing the user experience.
