I will agree with you on this. Apple is slowly trying to integrate typically Android ways of doing things (check the iOS 10 preview stuff they recently showed off, very Materialistic in certain places compared to what it used to look like), but they don't do any usability testing.

What pisses me off isn't specific cases like yours, what pisses me off is app developers don't ask themselves, in general, if what they're doing in the UX makes legitimate sense.

As in, eat your goddamned dog food, people.
