As was widely expected, 2011's Worldwide Developers Conference (WWDC) will take place from 6 - 10 June in San Francisco's Moscone West.

The five-day conference for developers will explore the future of iOS and Mac OS, Apple said.

“At this year’s conference we are going to unveil the future of iOS and Mac OS,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing.

“If you are an iOS or Mac OS X software developer, this is the event that you do not want to miss.”

Apple said that there will be more than 100 technical sessions presented by Apple engineers on a wide range of technology-specific topics for developing, deploying and integrating the latest iOS and Mac OS technologies at WWDC.

Additionally, more than 1,000 Apple engineers will be on hand to provide developers with code-level assistance, insight into optimal development techniques, and guidance on how they can make the most of iOS and Mac OS technologies in their apps.

It is expected that the iPhone 5 will be announced at this year's WWDC, though whether iOS 5 will be ready by then is under some doubt. Mac OS X 10.7 Lion is also expected to be launched.
