Storing and retrieving files is a fundamental task for any iOS app. The Swift programming language provides a number of powerful tools for working with files, including the `FileManager` class. With `FileManager`, you can create, read, write, and delete files, as well as manage directories and other file system operations.
There are many reasons why you might need to store and retrieve files in your iOS app. For example, you might need to store user data, such as preferences or settings. You might also need to store images, videos, or other media files. Whatever the reason, `FileManager` can help you get the job done.
