Sandbox deny file-read-metadata

Targets iOS

Hello all,

I’m currently trying to get a test build of my app onto an ipad. I’ve built the app and followed the “Ad Hoc Device Deployment” how-to. Now, when trying to run the application it crashes. The log contains several messages along the lines of

Oct 5 14:27:12 Andrews-iPad kernel[0] <Notice>: Sandbox: appNameHere(1050) deny(1) file-read-metadata /private/var/mobile/Containers/Data/Application/7632193D-7679-4DF4-9C6E-019165B5CFD7/.com.apple.mobile_container_manager.metadata.plist Oct 5 14:27:12 Andrews-iPad appNameHere[1050] <Critical>: Unhandled xojo.IO.IOException Reason: The file “.com.apple.mobile_container_manager.metadata.plist” couldn’t be opened because you don’t have permission to view it.

Which looks like some sort of permissions that are missing. I don’t suppose anyone has encountered something similar or has any suggestions for what might need done?

Thanks.
