Apple has released the first beta of iOS 9.2 for registered developers, build 13C5055d, available for iPhone, iPad and iPod touch.
Also available today is Xcode 7.2 beta as well.
With new betas, there are always issues in development. We’re told developers re-pairing Apple Watch may result in the stocks glance missing and the inability to sync music. Also, iCloud Keychain setup issues may persist, but rebooting the device will workaround the issue.
