Programmatically check if Core Data entities are indexed

Question

I am currently working with a library that sits between Core Data and the sqlite database (i.e. it handles a lot of the Core Data calls, and translates them into SQL queries). I have noticed that when creating the sqlite tables, it doesn't add any indexes. I have attempted to add in this functionality, but cannot see where the Core Data model 'Indexed tick box' property is stored.

I have access to every NSEntityDescription and NSAttributeDescription, which I would have assumed would be where the 'Indexed' property would be listed. However, the compoundIndexes array is nil and there doesn't appear to be another index property.

Answer 1

NSPropertyDescription has a isIndexed attribute.
(NSAttributeDescription is a subclass of this.)
