I guess im getting this error (3) because of the first 2 errors. I have been struck with this errors for the past 2 days and not proceeding further. It would be a great help if someone throws some light on how to solve this problem.

Thanks.

I don't have the complete answer it looks like the original error is due to your Core Data model. Check to see if you have a data model with the extension of ".xcdatamodel" instead of ".xcdatamodeld" for versions.

It looks like it is not able to compile your Core Data model until you convert the file.

Good luck!
