WWDC

Tim Bradshaw

Apple’s annual developer conference saw chief executive Tim Cook and head of software engineering Craig Federighi dominate the stage. Apple showed off new operating systems, including iOS8 and the newly-minted OS X Yosemite, as well as HealthKit, its first foray into fitness tracking, and HomeKit, a connected home platform. Not to mention tools for developers and a new programming language called Swift. Tim Bradshaw, Richard Waters and Sarah Mishkin give the rundown and reaction from the Moscone Center in San Francisco.
