Ah, didn’t even realise that was a thing (thanks). We should start calling iOS the “hidden gesture” OS. All these hidden swipes, overloaded gestures, etc., are examples of anti-patterns, not good design. Feels like iOS 11 suffers from a (hopefully temporary) bout of Androiditis https://twitter.com/rom/status/928940141221101578 …
Also good to know, thanks (and also a completely hidden gesture – both physically hidden and, in this case, temporally hidden).
