It seems like you're interested in the concept of "POP" in the context of Apple's WWDC sessions. The term "pop" appears in several contexts related to UI animations and transitions, particularly in the session titled "Enhance your UI animations and transitions" from WWDC 2024. This session discusses how pop transitions work in UIKit, including how they are handled when initiated by user interactions like tapping the back button or swiping back.
For more detailed information on this topic, you might want to check out the session Enhance your UI animations and transitions (05:11) where the mechanics of pop transitions and their cancellation are explained. This session also covers how these transitions are integrated into the UIKit view controller lifecycle and callbacks.
If you have any specific questions about this session or need further details, feel free to ask!
