The primary function of a Property List, often referred to as a plist, is to define application preferences and settings. Property Lists are commonly used in macOS and iOS development for storing structured data, such as user preferences for an application, configuration settings, and other data that an application may need to persist between sessions.

Using a plist allows developers to create a user-friendly way to manage these settings, as the format is easily read and written by both the system and the application. Plists can store various data types, including strings, arrays, dictionaries, and more, which helps in organizing the app’s configurations neatly.

This aligns with how applications rely on property lists for maintaining user experience and personalizing interactions without requiring users to dig into complex settings every time they use the app. Other choices do not pertain to the typical use of property lists, as they focus on different functionalities unrelated to application configuration and preferences.
