iOS target port for the engine is currently in development...
the plan is (far as I'm aware - currently) to add cross-platform support to VS, amongst other things for the next release, which should (hopefully) be ready sometime this year.
By cross-platform I mean: windows, apple mac, linux, iOS & android.
I've not heard of that Haxe engine before (I do have bad memory though) so will look it up the morrow
*edit:
http://haxe.org/ ? yeah not heard of it before.
