On the app I'm working on, an issue was encountered when submitting the app to store:
We have discovered one or more issues with your recent delivery for
"Application X". To process your delivery, the following issues must
be corrected: Unexpected CFBundleExecutable Key - The bundle at
'/Payload/(location of resources.bundle)/Info.plist'
does not contain a bundle executable. If this bundle intentionally
does not contain an executable, consider removing the
CFBundleExecutable key from its Info.plist and using a
CFBundlePackageType of BNDL. If this bundle is part of a third-party
framework, consider contacting the developer of the framework for an
update to address this issue. Once these issues have been corrected,
you can then redeliver the corrected binary.
