Error uploading to iOS App Store: ERROR ITMS-9000 "This bundle is invalid"

Question

When we try to upload a new version of our app to Apple's App Store we get the following error in Application Loader:

ERROR ITMS-9000: "This bundle is invalid. New apps and app updates submitted to the App Store
must be built with public (GM) versions of Xcode 5 and iOS 7 SDK. Do not submit apps built with
beta software." at SoftwareAssets/SoftwareAsset (MZItmspSoftwareAssetPackage)

We are already building with the latest available version of Xcode, 5.1.1 (downloaded from the Mac App Store) and v7.1 of the iOS SDK (which came with Xcode 5.1.1).

Our app is built with Marmalade 7.2.1. We've tried rebuilding all of the EDK extensions and static libraries that our app uses.

What could be going wrong? Is there anything more anyone else can tell us about the error to help us track it down?

Answer 1

Starting May 15, 2014, new apps and app updates submitted to the App Store must be built with Xcode 5.1.1

You have to update your xcode.
