How does the process work from building an app in the Corona SDK to publishing it to the Apple Appstore?

Are you familiar with certificates and provisioning profiles? If not it will be a long answer, but if so;

1. Write your app
2. Build your app
3. Create your app's profile in iTunes connect
4. Upload your app using App Loader (Apple's uploading tool)
5. Wait between 5 to 10 days to go into review
6. Wait between 1 and 3 days to get reviewed
7. If approved, appear on the store within a couple of hours.

Make sense? :)

But how does the process work between the corona sdk and xcode?

Xcode isn't involved in any way you need to worry about; you have the latest version on your Mac and you have your provisioning profile installed, then Corona will use that when you compile.

The pass 4 (4. Upload your app using App Loader (Apple's uploading tool)) change with xcode 4. Organize in xcode 4 make the upload. How this work now?
