Apple issues third betas of iOS 9.2 & OS X 10.11.2, second tvOS 9.2 beta to developers

iOS 9.2 beta 3, identified as build 13C5071, is now available to download on registered developer devices. It's accessible as an over-the-air update, or through the Apple Developer Center.

The update arrives just one week after iOS 9.2 beta 2 was released. A public release of beta 3 is likely forthcoming this week.

The most notable change in iOS 9.2 revealed by Apple is a change to how the Safari Web browser works in third-party apps, enabling user-installed extensions to operate in those conditions. It also supports AT&T's forthcoming NumberSync technology for receiving phone calls across devices.

The third beta of OS X 10.11.2 also arrives just one week after the second beta build. Developers have once again been asked to focus their testing on Calendar, graphics, Mail, networking, Notes, Photos, Spotlight, USB, and Wi-Fi.

Accordingly, there is a new third beta of Xcode 7.2 available to build apps for the latest updates to iOS 9 and OS X El Capitan.

Finally, Apple has also issued a second beta of tvOS 9.1 for testing. Its first beta arrived a week ago, and it is only compatible with the new fourth-generation Apple TV with Siri Remote.
