Hello,
when I select my data model in the xcode project, and then select Design/Data Model/Add Model Version I do get a new bundle in Xcode project, but now copy of the existing datamodel. The bundle, both in Xcode and on the Finder level, is empty. The app does not compile any more.
The only thing that might be unusual in this project - as far as I can tell - is that I have iVars in the ManagedObject classes that calculate some things on the fly, based on regular attributes. Could this be a reason for trouble?
I have no idea why this is going wrong, and would appreciate some help, greatly.
Thanks,
Rainer_______________________________________________
