Worldwide Developers Conference", which is held regularly by Apple Inc. in California every year. The main purpose of the conference is for Apple to show the latest software and technology to developers. It is the Pokemon Go for Apple developers, and the annual opportunity to "catch" Apple engineers to chat (one Apple employee in every 6
people); It is a Disneyland for Apple developers, and besides interesting lectures, there are also surrounding areas that must be grabbed. It may also be the world's largest offline dating site for Apple developers. Almost everyone knows the code in the venue, coffee shop or bar.
