Following today’s WWDC keynote where Apple discussed Mac OS X Lion, iOS 5 and iCloud the company has now released a slew of updates for registered developers. Apple has released the first beta of iOS 5, as well as iTunes 10.5. The fourth preview of Mac OS X Lion is also available. Registered developers can also enable iCloud for testing with their own apps.
Apple has also released Xcode 4.2 developer preview.
The first build of iOS 5 is available for iPhone 4 (GSM and CDMA), iPhone 3GS, iPad, iPad 2, iPod touch (3rd and 4th generation) and is labelled build 9A5220p. The beta of iOS is also accompanied by an update to iTunes which brings the extensive media software to version 10.5. iTunes 10.5 brings some minor graphical interface changes and of course adds support for iCloud, in this case Automatic Downloads of Music, Books and and Apps.
The features available in iOS 5 are covered in detail by World of Apple’s keynote coverage, over the coming days we’ll be offering a more detailed look at Apple’s brand new version of iOS.
Mac OS X Lion DP 4 is labelled build 11A480b and is available for registered Mac developers from the Developer Center. Apple today demoed many of the features we’ve already seen in Mac OS X Lion. With the release of the fourth developer preview iCloud will be the biggest changes. World of Apple will be looking in more detail at what has changed in developer preview 4 soon.
The big one for developers today is early access to iCloud. Such access will give developers time to build the services available into their apps. Apple has posted a detailed iCloud page just for developers which tells them what they need and how they get started with iCloud. Notably Apple has posted a beta of iPhoto which has Photo Stream built-in.
Finally Apple has released a beta of Safari 5.1 which includes a number of new APIs for developers, those that initially stick out are, “support for full-screen web content”, Extension Popovers API, and Extension Menus that can show a list of options from within the Safari UI.
