I can access the notification received from `NSManagedObjectContextObjectsDidChangeNotification` when I add/edit/delete Core Data values.

I am getting the following data from `userInfo`:

```
Optional([deleted: {(
    <Product: 0x7f8d1a634370> (entity: Product; id: 0xd0000000002c0000 <x-coredata://A9A941BF-C4BA-4E1F-972D-F188032C93E0/Product/p11> ; data: {
    amount = 54;
    date = "2016-01-10 17:16:53 +0000";
    name = test65;
})
)}, managedObjectContext: <NSManagedObjectContext: 0x7f8d1a705040>])

```

But I can't managed to retrieve the Product object that changed, so I can access his attributes (amount, date, name). 

I can see there is a [`NSObject: AnyObject]` dictionary, but still I can't get the object.
