Apple quietly posted this announcement requiring all iOS developers to “Build Your Apps With Xcode 5.1.1″. Apple enforces this when you try to upload your binary to the iTunes App Store:

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 or higher and iOS 7 SDK. Do not submit apps built with beta software.”

Today, we’ve addressed this in the last public release (2189). Just rebuild and submit. You can also use daily builds 2306 or later.
