Yesterday, Apple seeded the first beta of iOS 9.2 (Build number: 13C5055d) to developers. New version includes improvements to Live Photos, over 150 new emoji characters such as taco, burrito, cheese, wedge, middle finger, unicorn head. iOS 9.2 beta 1 also brings several bug fixes and enhancements related to Safari View Controller. Third-party Action Extensions will now work with the Safari View Controller, which is the new window that opens up when you click on a link in some apps.
iOS 9.2 beta 1 now available for download at Apple Developer Center, those registered with the Apple Developer Program can directly download new firmware from the Center.
Presumably iOS 9.2 beta 1 will be released to users participating in the general public beta program as well. Any user can choose to join the public beta program by signing up to use pre-release software here on Apple.com, though it’s generally only recommended for advanced users as beta software tends to be buggier and less stable than a final release.
