Faced here with this problem. Already reread a bunch of forums, but never found a solution to the problem.
App Store Connect
We identified one or more issues with a recent delivery for your app, "Edless Agent". Please correct the following issues, then upload again.
Invalid Signature - A sealed resource is missing or invalid. The file at path [Name App.app/Name App] 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 developer.apple.com/library/ios/documentation/Security/Conceptual/CodeSigningGuide/Introduction/Introduction.html

Who faced the same problem. I decided to rename it all the sprites in the game in English.
