iOS 11 beta 10 is pushed out to developers0
If you're already on the developer beta profile, simply go to Settings –> General –> Software update in order to install the update. Make sure that you have enough space on your iOS device so that the developer version of the new build fits. We would expect the public beta to be made available to Apple's public beta testers shortly.
Among the changes we expect for iPhone users with iOS 11 is a customized control center, a feature that allows you to offload apps you barely use to increase the amount of storage on your iPhone, the ability to make peer-to-peer money transfers using Apple Pay Cash, new AR features, an improved lock screen and more. Apple iPad users will receive a new dock, drag and drop capabilities for icons, files and more, and improved multitasking.
