Registration is now open for WWDC 2016 ahead of its June 13 start. Developers interested in attending can head to the WWDC 2016 website now to register for the lottery-style attendee selection process through April 22 at 10 a.m. PDT. After registration closes, Apple will then randomly select attendees from those who have registered. If you happen to win entry through the lottery, you'll be notified by April 25 that you can purchase your ticket, Apple says.

Apple kicks off WWDC 2016 registration

From Apple:

"With four innovative operating systems and a new, intuitive programming language powering over 1 billion devices worldwide, there has never been a more exciting time to bring our developer community together," said Philip Schiller, Apple's senior vice president of Worldwide Marketing. "WWDC 2016 is going to be a landmark event for developers who are coding in Swift, and building apps and products for iOS, OS X, watchOS and tvOS. We can't wait for everyone to join us — in San Francisco or through the live stream."

WWDC offers developers a chance to sit in on a number of sessions geared towards building apps for all of Apple's platforms. In addition to seeing any new goodies Apple has up its sleeve for the day one keynote, attendees will get to interact with over 1,000 Apple engineers and thousands of fellow developers from around the world.
