Core Data - incompatible Model while pre-populating data

Question

I am getting this error while adding pre-populated data in new project in Xcode .

}

I tried ... resetting content and settings .. model versioning of the data model .. but not worked... however if there is only one entity is there then there isnt any error like this .this error comes up when there is more than one entity.

I had a similar problem (not the exact same one though) which was caused by me making a change to the model after the SQLite database file had been created. I had to delete the SQLite database from the Debug folder (which should be created where your application is compiled to) and then build the application again. A new SQLite database was created with my updated model. Hope that makes sense and is of some help.

Updated:

this and other suggested solutions can be found elsewhere on stackoverflow:

The model used to open the store is incompatible with the one used to create the store

Hey cullener ... I am running this app in iphone simulator .. can you please tell me where this folder [Debug folder (which should be created where your application is compiled to)] is ? – Jean-Luc Godard Feb 28 '14 at 00:52
do you mean the folder in library where the app is crated ? I tried that one to .. I deleted it .. even from the trash , but it dint work – Jean-Luc Godard Feb 28 '14 at 00:54
have a look in /Library/Developer/Xcode/DerivedData for a folder that starts with the name of your application. check in there to see if there's an older version of your SQLite database – cullener Feb 28 '14 at 01:07
are you sure that the entities in your model match your database exactly? – cullener Feb 28 '14 at 01:30
yes it does..however there is a huge list of entity there .. let me make it again .. will get back to you after doing it .. – Jean-Luc Godard Feb 28 '14 at 01:31
clean your project after making the entity again – cullener Feb 28 '14 at 01:41
