Answer 1

You should do following steps

1. Delete the application and Run it again, if it still shows the same error. Then it means that, you used the specific attributes/attribute with different type.
2. Go to your .xcdatamodeled file and check the type of each attributes.
3. Go to your code and check, while inserting the attributes/objects in core data, you used the same type of different. So, the point is type(NSString, NSDate...) of the attributes/objects in your code and .xcdatamodeled should be same. If not then it will give the error "Error Domain=NSCocoaErrorDomain Code=134100"
