Xcode iOS organizer submit to app store yields “The archive is invalid” error

Question

I just switched from Xcode 3 to 4. When I attempt to upload an app that I have archived to the organizer, I receive this error:

The archive is invalid

Answer 1

If you are running an Xcode beta version (Apple calls it a "developer preview") you will get this error because you're not allowed to submit apps from a beta version. This restriction is not mentioned in the Read Me file or on the Xcode download page. To submit an app, you will need to uninstall Developer Tools, then reinstall the latest non-beta version, then restart your computer.

Here's the command-line command to uninstall:

sudo /Developer/Library/uninstall-devtools --mode=all
