Apple announces iOS 8, OS X update at WWDC

SAN FRANCISCO -- Apple's Mac operating system is getting a new design and better ways to exchange files, while new features in the software for iPhones and iPads include one for keeping tabs on your health.

Apple executive Craig Federighi pointed out that data from various fitness-related devices now live in silos, so you can't get a comprehensive picture of your health. That will change, he says, with HealthKit coming to the new mobile software, iOS 8. Apple is also working with the Mayo Clinic to make sure your weight, calorie intake and other health metrics are within healthy ranges.

Apple is also making it easier for various devices to work together. You can share songs, movies and books you purchase with your entire family. Macs and mobile gadgets will share more features, and you can share and sync files between the two more easily.

The company is previewing the new features at its 25th annual conference for software developers in San Francisco. Here are the highlights on what's been announced and what's coming:

CHANGES TO IPHONES AND IPADS:

ANNOUNCED EARLIER:

Last week, Apple announced a deal to pay $3 billion for Beats Electronics, a headphone and music streaming specialist. The deal brings rapper Dr. Dre and recording impresario Jimmy Iovine to undetermined roles at Apple. During a demo Monday, Federighi placed a call to Dr. Dre to welcome him to Apple.

COMING FOR THE HOLIDAYS:

Apple typically holds a separate event in September to announce new iPhones. Updates to the iPad are also likely, possibly at yet another event. Many analysts also believe the company will release an Internet-connected watch later this year as part of Apple's expansion into wearable technology.
