while uploading my iOS app with compiled with Air SDK 24, i get the following error : ERROR ITMS-90035: "Invalid Signature. A sealed resource is missing or invalid. The file at path is not properly signed. Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose "Clean All" in Xcode, delete the "build" directory in the Finder, and rebuild your release target. For more information, please consult https://developer.apple.com/library/ios/documentation/Security/Conceptual/CodeSigningGuide /Introduction/Introduction.html"
I am sure I am using the right certificates and provision profiles that are used for distribution. What could be any other possible issue with my upload?
