Which Apple application has a built-in property list editor you can use to edit .plist files?

The correct answer is Xcode, which is Apple’s integrated development environment (IDE) designed for developers. Within Xcode, there is a built-in property list editor specifically tailored for editing .plist files. Property lists are commonly used in macOS and iOS applications to store user preferences and configuration data. Xcode provides a user-friendly interface that allows developers to easily manipulate the structure of .plist files, whether they are in XML or binary format.

Using the built-in editor, developers can add, modify, or delete keys and values in a straightforward manner, making Xcode an efficient tool for dealing with .plist files during application development. The clarity and structure offered by this property list editor help maintain the integrity of the data within these files, which is essential for app functionality.

Other applications, such as TextEdit, can open .plist files but lack the specialized features necessary for proper editing, such as validation checks or hierarchical views. System Preferences typically uses .plist files to manage system settings but does not provide direct editing capabilities for .plist files. The Terminal can interact with these files using command-line tools but does not offer a graphical interface for editing, making Xcode the best choice for this task.
