On October 16, iOS 11.1 beta 3 became available for developers. And it's really worth installing.
And this is the first version of iOS 11 that just needs to be installed. Instead of smiles and non-critical edits, we finally improved the performance of iOS 11.
How to install
Registered developers can download the iOS 11 beta from the Apple Developer Center or over the air once you have a developer profile.
You can download a ready-made development profile and install it in 1 click.
