Persistence involves storing data on the disk in a way that allows retrieval without modification when the app is reopened. There are various methods available for data storage, ranging from simple to complex:

Storing data using data structures like arrays, dictionaries, sets, and other similar structures is an excellent option for intermediate storage.
NSUserDefaults and Keychains serve as straightforward key-value stores. However, NSUserDefaults is considered insecure, while Keychains provides secure storage.
NSFileManager enables the storage and retrieval of data (serialized or not) to and from a disk through file or disk storage.
Relational databases, such as SQLite, offer a robust solution for implementing complex querying mechanisms.
