Preview at WWDC likely in June, followed by September launch.
Apple Releases iOS 11.2 Beta 2 for iPhone X
Registered developers can download the iOS 11.2 beta from Apple's Developer Center or over-the-air once the proper configuration profile has been installed from the Developer Center.
Apple first released iOS 11.2 to developers and public beta testers earlier this week, but did not provide an iPhone X version. That left customers who had installed the iOS 11.2 beta on their previous devices unable to restore from an existing backup on the new iPhone X.
With the iPhone X beta now available, an iOS 11.2 backup can be installed on the device after upgrading to the new version of the software.
iOS 11.2 addresses an animation bug in the Calculator app that caused some numbers and symbols to be ignored when entered in rapid succession. The update removes the animations from the calculator app so calculations can be done quickly with no need to pause between entering numbers to obtain the correct result.
In addition to the Calculator bug, iOS 11.2 introduces a new Now Playing option for controlling content on the Apple TV in Control Center, redesigned camera emoji, and a new loading animation for Live Photos effects.
