– iPad App Switcher – When closing an app, the swipe to close gesture has been restored. Previously, it was necessary to hold down on an app and tap the “x” to close it when using the iPad’s App Switcher interface.
– SOS – When using Apple’s emergency alert feature, an SOS that’s canceled will no longer send out notifications.
– Files app – OS X Server and Dropbox have been added to the Files app on the iPhone and the iPad as new Locations.
– TV Providers – Comcast, Cox, AT&T U-verse, Verizon Fios, Time Warner Cable, and more are all listed as new providers in the TV Providers section of the Settings app in iOS 11 beta 3, and they appear to allow users to take advantage of Single sign-on.
– Notification Center – There’s no need to swipe a second time to see “Earlier Today” notifications in the Notification Center. All notifications are shown on the first downward swipe to get to the Lock Screen/Notification Center. In previous betas, you needed to swipe down to see unread notifications and then swipe up again to see earlier notifications. Beta 3 simplifies the Notification Center.
– iCloud Messages – The syncing feature that uploads your iMessages to iCloud in iOS 11 now lets you know how many messages still need to be uploaded.
– Screen Recording – When you 3D Touch the Screen Recording button in the Control Center, there’s a new option to start a broadcast. Right now, the feature works like a standard screen recording and saves a video to the Camera Roll, but it could perhaps integrate with third-party apps in the future for automatic uploads.
– Music – When a song is playing in the Music app, tapping the song name from the Control Center will once again open the Music app.
Notification Center here is the standout improvement. There were some grumblings in regards to how it was over complicating the notifications so it’s good that Apple appear to have improved and simplified this feature.
