Thanks for the reply.
I know I can download it from apple (I hope for free, as i am using it for personal needs) but, shouldn't it come bundled with the air? It is even listed in the specs sheet...
Yes, I know it should be on the restore DVD. It always was with my other macs.
The problem with the Air is that there is no restore DVDs anymore. It comes with a restore USB drive. And it seems that XCode is not in it.
