I am writing an Interactive book application(TheBlueJackal.xcodeProj).when I run the application it is working fine but when I tried to create .ipa (IPA file) and when I click on export button after selecting the corresponding provisioning profile I am getting the following error
Code signing operation failed Check that the identity you selected is valid.
I want to know when this error occur. I tried a lot in google but unable to find the correct reason. Can anyone please help me in understanding this error.
Thanks in advance.
