Is there any evidence to support that assertion?
I have many colleagues who work on phones. The patterns I see
are that
the iOS guys who use Obj-C never complain about it, and the GC
guys
are often struggling with it.
The bias in gamedev is strongly towards iOS too, so that should
be a
more populous group to draw samples from.
You conflate freezing and performance. ARC easily can be slower
but is has benefit of slowdown distributed more evenly thus not
obviously notable.
