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

Never try to submit using apps you built using beta SDKs as your base SDK.

I got rid of this problem by uninstalling all developer tools with the below command

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

and then restarted my system and installed that latest non-beta version of XCode and non-beta iOS SDK.
