Every year, Apple holds a Worldwide Developers Conference near its Cupertino campus in California to give thousands of developers from around the world a chance to meet up with Apple engineers and attend valuable workshops and software development sessions.

For many years, WWDC was hosted at the Moscone Center in San Francisco, but starting in 2017, Apple moved to the McEnery Convention Center in San Jose, California, where this year's conference was also held. WWDC 2019 took place from Monday, June 3 to Friday, June 7.

Apple kicks off each conference with a keynote on the first day, where the company makes major announcements and sets the stage for the rest of the week. Media invites for the June 3 keynote event went out on May 22.

Keynote events typically offer a look at upcoming products and provide the first details on new operating systems, though in some years there are no hardware announcements and the focus of the event is software.

In 2019, we saw updated versions of iOS (including a new iPadOS specifically for the iPad), macOS, watchOS, and tvOS, all of which will gain new features and capabilities. We also got a preview of the new Mac Pro and Apple Pro Display XDR, both launching in the fall. Read on for our event preview published prior to WWDC.

The 2019 Worldwide Developers Conference was easily one of the most exciting events of the year, with Apple introducing feature after feature over the course of a two and a half hour event. For those who don't want to rewatch the entire keynote, we condensed everything Apple announced into 9 minutes, so you can get a quick recap of everything important.

Apple debuted new versions of iOS, iPadOS (now separate from iOS!), macOS, tvOS, and watchOS, all of which have a long list of new features, plus Apple gave us a peek at the new Mac Pro and 6K Apple Display. In addition to our video, there's a recap of all of our coverage below, giving you a complete overlook of everything new.
