Problems with iOS7 Beta

Hey everyone,

I am trying to get my app to run on iOS7 beta, but it always fails with the following error found in the Device Log:

Jul  8 13:31:24 installd[62] <Notice>: 0x201000 MobileInstallationInstall_Server: Installing app mobileclient
Jul  8 13:31:24 securityd[86] <Error>:  SecOSStatusWith error:[-34018] The operation couldn’t be completed. (com.apple.security.osstatus error -34018 - client has neither application-identifier nor keychain-access-groups entitlements)

Does anyone know what I should do?

Thanks in advance jp99
