about app updates and ios7

[jianjiang]

We learned that :

Starting February 1, new apps and app updates submitted to the App Store must be built with the latest version of Xcode 5 and must be optimized for iOS 7. Learn more about preparing your apps by reviewing the iOS Human Interface Guidelines.

Now I try update app to app store but was rejected. Any idea?

ERROR ITMS-9000: "This bundle is invalid. New apps and app updates submitted to the App Store must be built with Xcode 5 and iOS 7 SDK." at SoftwareAssets/SoftwareAsset (MZItmspSoftwareAssetPackage)
