What storage methods for objects exist in the iOS platform?

In iOS, objects can be stored in several ways:

• UserDefaults — for storing small settings and simple data (strings, numbers, boolean values).
• File system — saving files in the application's directories (Documents, Caches, etc.).
• Core Data — an object-oriented database for complex structured data.
• Keychain — secure storage for confidential data, such as passwords.
• NSCoding / Codable — serialization of objects into files or UserDefaults.

Example of saving a string in UserDefaults:

UserDefaults.standard.set("Example", forKey: "myKey")

The choice of method depends on the volume, structure, and security requirements of the data.
