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

I tried most of the ideas above, and they did not work for me, likely because I am using he Appcelerator Titanium platform. I did however delete the Build directory and re-built the product and it passed the validation and I was able to upload the binary to the app store.
