We are actually trying to upload our Xamarin application to AppStore and we are getting the following error message:
Invalid Signature - Code object is not signed at all. 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

It seems the problem is linked to an external library we are using, that we can not sign.
We have followed the steps in Xamarin documentation to build the ipa and sign the application but we still get the above error.
Is there something specific we need to do in Xamarin Studio to sign an external library before we upload it to AppStore?
If yes can someone guide us through these steps because we can't find anything on this?
