Today is the start of WWDC, Apple’s developer conference. At 10 am Pacific / 1 pm Eastern today, Apple CEO Tim Cook and other Apple executives will give the keynote address, an event Apple typically uses to preview new iPhone, iPad and Mac software — and this year, I’m sure we will hear about the Apple Watch as well. This is typically an event where Apple previews the next version of the iOS operating system, so my guess is that we will learn about some of the new features in iOS 9, which will likely be released later this year when the 2015 model of the iPhone is released. There are also rumors that Apple will debut a new Apple Music service today.
You can watch the keynote live at apple.com/live, using Safari on a Mac, iPhone or iPad. The live stream is also available on Apple TV.
