Instance Property


The compound indexes for the entity as an array of arrays.


var compoundIndexes: [[Any]] { get set }


The arrays contained in the returned array contain instances of NSAttributeDescription, NSRelationshipDescription that represent properties of the entity, or of NSString that match the name of attributes or relationships of the entity.

Compound indexes are only used by stores that natively support compound indices—setting them is only advisory. Indexes apply to the entire inheritance hierarchy.
