The Apple Worldwide Developers Conference (WWDC, also known as Dub Dub) is a conference held annually by Apple Inc. in San Jose, California. Apple uses the event to showcase its new software and technologies for software developers. Attendees can participate in hands-on labs with Apple engineers and attend in-depth sessions covering a wide variety of topics.

WWDC began in 1987 in Santa Clara. After 15 years in nearby San Jose, the conference moved to San Francisco, where it eventually became Apple's primary media event of the year and regularly sold out. WWDC returned to San Jose 13 years later.


A $1,599 ticket is required to enter the conference. Tickets are obtained through an online lottery. Scholarships are available for students and members of STEM organizations. Attendees must be 13 years or older and must be a member of an Apple Developer program.

Until 2007, the number of attendees varied between 2,000 and 4,200; however, during WWDC 2007, Steve Jobs noted that there were more than 5,000 attendees. The WWDC events held from 2008 to 2015 were capped, and sold out at 5,000 attendees (5,200 including special attendees). WWDC 2018 had 6,000 attendees from 77 countries, including 350 scholarship recipients


WWDC is held annually from Monday through Friday on one week in June. The conference consists primarily of a keynote address, presentation sessions, one-on-one "lab" consultations, and special get-togethers and events.

The conference begins with a Monday morning keynote address by Tim Cook and other Apple executives. (From 1998 until his resignation and death in 2011, Steve Jobs gave the keynote address, which the media often called the Stevenote.) It is attended by both conference attendees and the media, since Apple regularly makes product announcements at the event. Hardware announced during the address is sometimes exhibited in the conference hall afterwards. The keynote address is followed in the afternoon by a Platforms State of the Union address, which highlights and demonstrates changes in Apple's software developer platforms that are detailed in sessions later in the week. The Apple Design Awards are also announced on the first day of the conference.

Several session tracks run simultaneously from Tuesday through Friday. The presentations cover programming, design, and other topics and range from introductory to advanced. Almost all regularly scheduled presentations are delivered by Apple employees. These presentations are streamed live, and recordings can be viewed on demand on the Apple Developer website in the conference's iOS and tvOS applications. Lunchtime sessions are given by a variety of guest speakers who are industry experts in technology and science; these sessions are not streamed or recorded. In the past, some sessions included question-and-answer time, and a popular Stump the Experts session featured interaction between Apple employees and attendees.

At the labs, which run throughout the week, Apple engineers are available for one-on-one consultations with developers in attendance. Experts in user interface design and accessibility are also available for consultations by appointment. Apple organizes social get-togethers during the conference for various groups, such as women in technology or developers interested in internationalization or machine learning. The Thursday evening Bash (previously the Beer Bash) at a nearby park features live music, food, and drinks for all attendees 21 years or older.
