Apple Seeds Second Beta of iOS 11.1 to Developers and Public Beta Testers With New Emoji
Registered developers can download the iOS 11 beta from Apple's Developer Center or over-the-air once the proper configuration profile has been installed from the Developer Center.
Apple said the second beta of iOS 11.1 introduces a range of new Unicode 10 emoji like crazy face, pie, pretzel, t-rex, vampire, exploding head, face vomiting, shushing face, love you gesture, brain, scarf, zebra, giraffe, fortune cookie, pie, hedgehog, and more.
Several emoji have also seen some small design changes in iOS 11.1, including the dolphin, octopus, bee, snail, and whale characters, among others.
A few other small features were discovered in the initial iOS 11.1 beta. The built-in keyboard in iOS 11.1 now offers up multiple emoji symbols when using an emoji-related word like "cake" or "happy," with each of the suggestions displayed at the end of the predictive text suggestions. There's also an updated camera icon under Restrictions, a new animation when tapping the status bar to scroll upwards, and a faster unlock animation.
iOS 11 marks a major update to the operating system with systemwide design tweaks, a new Lock screen experience, a revamped Control Center, ARKit, new app features, and an entirely new interface for the iPad that includes a Dock, Drag and Drop support, and a redesigned App Switcher for better than ever multitasking.
Update: Apple has also released the second beta of iOS 11.1 to public beta testers.
