Property Lists and Archiving

When your app closes, all its in-memory data disappears. To keep user settings, game progress, or other important information, you need data persistence.

Data persistence means saving data to a permanent storage location, like a file on the device, so it can be retrieved later.

Property Lists (PLists) are a standard way for iOS apps to store structured data. They're XML or binary files that represent common data types.

• Supported Types: NSString, NSNumber, NSDate, NSData, NSArray, NSDictionary.
• PLists are great for small, hierarchical data like user preferences or configuration settings.
