No. It is not. OS X (and 9, 8 and older I suppose) are on topic and we overlap with ask different there. IPhone questions are off topic unless there is a computer involved. IPads are tablets and are kinda on topic 

So no, unless you're the op, don't flag that sort of thing for migration. If you are, we may migrate depending on the circumstances - though, its always better to ask questions on the site you feel is best in the first place.
