The small swipe gesture to remove an item from a list of IOS is now protected by patent (US 7,934,156 ). This patent is part of the vast body around the tactile manipulation introduced in 2007 to protect the innovations of IOS.This patent counts Scott Forstall among the inventors is not limited just to this gesture, but is interested in mechanics to fine tune the action. To remove an item from a list, it sweeps from left to right, then a button appears on which you can enter to confirm. But if you type in hand, it does not delete, a mechanism to avoid errors.
A move that seems natural and obvious, but is one of those little details that form the "identity", the "look and feel" of IOS, a central point of confrontation between Apple and Samsung (read: Apple and Samsung: small trial with friends ).
