Apple executives seemingly did very few interviews after the iPhone event three weeks ago. The best, perhaps by far, is this 11-minute video with Craig Federighi by “Daniel Decodes”, a Chinese language creator. His YouTube account only has 1,100 followers (and only had had 500 at the time of the video) and only one other video — presumably he’s got a big following in China. Very insightful questions about the Duo user interface — and Federighi gives very thoughtful answers. The question (and answer) about “back” swiping really gets to the heart of what makes iOS so much more cohesively designed than Android, spatially.
