Apple today released a handful of new beta versions of its core operating systems.
These betas are specifically for developers, rather than public beta testers. App writers can download and test beta 3 of iOS 10.2, macOS Sierra 10.12.2, and tvOS 10.1, and beta 2 of Xcode 8.2.
Previous beta releases of iOS 10.2 show the platform includes Unicode 9 with a fresh batch of emoji, as well as new wallpapers, iMessage screen effects, camera settings, video widgets, and emergency contact alerts.
Apple typically makes the public beta available a day or two after the developer beta.
