Preview at WWDC likely in June, followed by September launch.
Apple Releases Second Public Beta of iOS 10
Beta testers who have signed up for Apple's beta testing program will receive the iOS 10 beta update over-the-air after installing the proper certificate on their iOS device.
Those who want to be a part of Apple's beta testing program can sign up to participate through the beta testing website, which gives users access to both iOS and OS X betas. The video below will walk you through the necessary steps for installing the iOS 10 beta to give the new features a try. Betas are not stable and include many bugs, so they should be installed on a secondary device.
The second public beta of iOS 10 and the third developer beta of iOS 10 are likely identical, and in the developer beta, Apple introduced a new keyboard sound, an Accessibility option for using iOS 9-style Touch ID, haptic feedback when locking an iPhone, improved Quick Actions for sharing apps, and more.
iOS 10 includes a number of new features and design tweaks, like a new Lock screen experience, a revamped Messages app with background animations, bubble effects, Digital Touch, a full App Store and more, and a Photos app with impressive facial and object recognition capabilities.
There's a new Home app, and apps like Maps and Apple Music have been redesigned, plus there are hundreds of smaller tweaks and changes in the operating system, which we cover extensively in our iOS 10 roundup.
iOS 10 is available to developers and public beta testers at the current time, with a public release planned for the fall.
