Apple developers' conference in US from June 5

"WWDC 2017" will give developers access to more than 1,000 Apple engineers with opportunities to meet and engage with them throughout the conference.

"Each year during WWDC, millions of talented developers around the world learn about Apple's breakthrough platform technologies ranging from programming languages like Swift to breakthrough developer APIs like SiriKit, HomeKit, HealthKit and CarPlay," Apple said.

The conference will be live-streamed through the Apple developer website (developer.apple.com/wwdc) and on the WWDC app for iPhone, iPad and Apple TV.

In addition to the keynote address, get-togethers, sessions and labs for developers, Apple is working with the city of San Jose and local businesses to celebrate the return of WWDC with very special experiences around San Jose throughout the week.
