Years pass and traditions repeat themselves: six days before the beginning of Worldwide Developers Conference 2015, Apple today started decorating the Moscone Center (in San Francisco) with its traditional giant white apple.

Gradually we will follow with you the progress of the preparations there. Soon, they will also have to paint some themed banners inside the convention center including possibly confirmations of iOS 9 and OS X 10.11.
WWDC 2015 will take place from the 8th to the 12th of June, but most of the attention is just for its opening keynote on Monday. Check out all the related rumors we've published here.
