ARC, or Automatic Reference Counting, is a memory management feature used in Apple's programming languages like Swift and Objective-C. It automatically manages the memory of objects by keeping track of and releasing objects that are no longer needed, thus preventing memory leaks. While ARC itself is not specifically mentioned in the provided WWDC context, it is a fundamental part of app development on Apple's platforms, ensuring efficient memory usage and performance.
