Hi,
To be honest I don't really know. I have an entity called Idea, and a string attribute of 'description' Xcode4 really doesn't like this and crashes. I can change the attribute name in a new data model, but can I then remove the old models and just leave the mapping models to deal with upgrading the file?
Many Thanks
Amy Gibbs

This didn't appear as an error in Xcode 3 which I was using, and didn't create a problem using the app. Now in Xcode 4 the model won't even open due to this error. I have got a version of Xcode on a 10.6 machine I can use so I have created a new model version that changes the attribute name to 'ideaDecription'.
