What is the name of Apple's annual worldwide developer conference?

Apple’s annual worldwide developer conference is called the Worldwide Developers Conference.

The event is commonly abbreviated WWDC. Apple uses it to present software updates, developer tools, application programming interfaces, and sometimes new hardware. Its keynote has become one of the most prominent annual events in the technology industry.

The first WWDC took place in 1983, although the event’s format and public visibility changed substantially over time. Apple traditionally held it in California, later adopting online and hybrid formats so developers worldwide could participate.

WWDC is different from a product-only launch event. Its central audience is software developers who build for Apple platforms such as iPhone, iPad, Mac, Apple Watch, and Apple TV. The conference name refers to developers worldwide, not to a particular operating system.
