The article is overly critical and does not acknowledge either the technical debt nor the complexity inherent in doing even simple changes to something as complex as iOS at this point. Still, lots of points are valid, especially about non-obvious gestures.<p>In general I do everything I can to avoid using gestures. A lot of apps with heavy use of gestures use a one-time tutorial that explains gestures to a new user but that just admits that there&#x27;s a UX failure to me. I like the idea of having a standard way to check all of the available gestures at any given time. Maybe there is even a way to convey that with simple font, style or color usage but getting everyone to get on board to that level of detail seems impossible. Without such a system, every gesture should be ultra obvious. Even something as simple as having a thumbnail partially cut off to signify that there are more thumbnails viewable upon a swipe gets the job done.
