I have an apple account and I have downloaded XCode on my Mac. Now... What if I download XCode on my friend's Mac becauase he doesn't have an account yet and he would be on the iOS program later. Also he wants to make iOS apps. Would he be able to upload it as his app (saying he downloaded Xcode with my account and he now have an apple account)? Should he re-download the App again (with his account)?

Thanks in advance.
