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 5.1.1

I submitted my IPA file to Itunes Connect using Application Loader and got the error message below. I have AIR SDK 13.0.0.111 and using Flash Builder 4.6.

Please help. Thank you in advance.
