Apple just announced the dates for its annual Worldwide Developer’s Conference (WWDC). It will run from June 8 to June 12 this year. WWDC is a huge event each year, and as its name implies it’s focused around developers. However, it’s also where Apple often reveals its next updates to OS X and to iOS. That means we might learn about the successor to OS X Yosemite and iOS 8.

On Monday evening, for example, the first iOS 8.4 beta rolled out. It packs Apple’s latest redesign of its music player, which the company is expected to discuss in detail during WWDC 2015. That’s when we hope to learn about what Apple’s plans are for the Beats streaming music service, too, which will presumably be rolled into its music player.

“WWDC will feature more than 100 technical sessions, over 1,000 Apple engineers, hands-on labs to help developers integrate new technologies and fine tune their apps, as well as the Apple Design Awards which showcase the best new apps in the last year,” Apple said.”

Registration will close on April 17, at 10 AM PT and that folks selected to attend will be alerted on April 20. Tickets cost $1,599.
