iOS 11.1 Beta 2 Brings Back 3D Touch App Switcher
The feature was "intentionally removed" during the iOS 11 beta testing process and was not reimplemented ahead of the official iOS 11 launch, but Apple software engineering chief Craig Federighi promised it would be re-added in a future iOS 11 update.
In an email to a MacRumors reader, Federighi said the feature needed to be temporarily removed in iOS 11 because of technical issues.
We regretfully had to temporarily drop support for this gesture due to a technical constraint. We will be bringing it back in an upcoming iOS 11.x update.The gesture, first implemented in iOS 9, allows users with a compatible iPhone to 3D Touch at the left edge of the display to bring up the App Switcher. When it was pulled from the beta, many iPhone users were disappointed as it is a convenient method for switching between apps with a single gesture. Sans gesture, the only way to bring up the App Switcher on an iPhone is by a double press on the Home button.
Thanks (and sorry for the inconvenience)!
iOS 11.1 beta 2 is currently available for developers, but a public beta should be coming later this week. We're still early in the beta testing process, so it's not yet clear when iOS 11.1 will see a public release.
