Apple's splashy developer fest kicks off June 8

Apple announced Tuesday that the 2015 edition of its Worldwide Developers Conference will run from June 8 through June 12 in San Francisco.

The highlights of the annual WWDC event for Apple users and developers alike typically are new details and demonstrations of the next generations of the Mac OS X software and the iOS mobile operating system, which this year will be iOS 9.0.

This year's event will come just two months into the Apple Watch era. The company's first-ever wearable gadget will get into customers' hands starting April 24, following the launch of preorders Friday.

Another early 2015 arrival in Apple's device lineup is a slim new 12-inch MacBook .

At last year's WWDC, Apple demoed Mac OS X 10.10 Yosemite and iOS 8.0. Now running on the new MacBook and on other Mac computers, Yosemite introduced some novel features, such as Handoff, which lets you switch tasks between your Mac and your mobile device. The centerpiece of the Apple Watch and the latest iPhones and iPads, iOS 8 introduced a Health app and Apple Pay, the company's new mobile payments system.

Apple is already promising forward movement for its PC and mobile operating systems.

"We've got incredible new technologies for iOS and OS X to share with developers at WWDC and around the world, and can't wait to see the next generation of apps they create," Philip Schiller, Apple's senior vice president of worldwide marketing, said in a press release.

For developers, Apple engineers at WWDC 2015, to be held at San Francisco's Moscone West convention center, will present more than 100 technical sessions on a range of topics for developing, deploying and integrating the latest iOS and OS X technologies. More than 1,000 Apple engineers will be holding hands-on labs to help developers learn how to work with the new OS versions in their apps.

Apple will also hold its Design Awards to highlight apps for the iPhone, iPad, Apple Watch and Mac that "demonstrate technical excellence, innovation and outstanding design."

Individual tickets sold in the United States will cost $1,599, and tickets will be sold in local currency in other countries where available. Developers and other interested parties can try to score a ticket at the WWDC website starting now until Friday at 10 a.m. PT.

Tickets will be doled out on a random selection process, and you'll know by Monday at 5 p.m. PT if you're one of the lucky ticket holders. Tickets sell out fast, so those of you who would like to attend should register as quickly as possible.

You'll need an Apple developers account in order to register for the conference. Specifically, you need to be a current member of the iOS Developer Program, the iOS Developer Enterprise Program or the Mac Developer Program as of Tuesday morning's announcement of WWDC. Developers age 13 through 17 must have their submissions completed by a parent or guardian who is an eligible member.

As many as 350 free tickets will also be given to students and members of participating STEM organizations around the world through WWDC scholarships, and those participants don't need to have a paid developer program membership.

Last year, Apple handed out 200 scholarship tickets by working with the National Center for Women & Information Technology. This year, it will expand its partnership to more than 20 organizations -- such as Black Girls Code, Coalition for Queens, Latinos in Information Science and Technology Association, and #YesWeCode -- in an effort to bring more diversity to WWDC.

Scholarships are open to students and members or alumni of listed STEM organizations who are 13 years of age or older. Submissions will be accepted from April 22 to April 26 at 5 p.m. PT.
