I reinstalled Corona Enterprise and now it works. Sorry for the red herring.
The default project builds successfully for iPhone simulator, but when I put my own Corona project in the /Corona folder, it fails, saying:

What files/settings within the Corona folder would affect Xcode’s ability to codesign the build?
Thanks
