I don't see why/how – they are _completely_ different UI interaction models. Superficially it looks similar, but the one thing that really set iOS apart, was to build UI concepts that targeted finger interaction first (UINavigationController and UITableView are stroke of genius).

Everything from how big the area for a tap is, to how to work with highlights, how dragging work, how things are aligned, what deliberate limitation etc, are different between macOS and iOS.
