Data model support non-standard attribute: id

mazllia commented 10 years ago

This is the Core Data Reference: Non-Standard Persistent Attributes identifying how you can do to support non-standard attribute object type.

The difference between the approaches is that with transformable attributes you specify just one attribute and the conversion is handled automatically. In contrast, with transient properties you specify two attributes and you have to write code to perform the conversion.

This issue depends on #5.
