Multiple Content type reference

I am using Persistence Framework to Sync data, and I am stuck at one point where I have multiple contenttype as reference in my Product content type:

  • Content [Book, Electronic, Applience]
    How can I achive this in my Coredata as we can only reference singal Entity?

Can you make an abstract core data entity(Product) and mark it as parent of your different types(Book, Electronic, Applience)?


It work for me. If any one want to learn abstract core data entity here is link
