I remember reading somewhere about multi-column indexing in Core Data (iOS), but I can’t find that information anywhere.

Is multi-column indexing possible with iOS5 Core Data?

I can set up multiple indexes on single columns, but can’t find an option for multi-column index.

    I found what I was looking for in WWDC 2011 videos, what’s new in Core Data (iOS5).

    They call this “compound indexes”, and they are set by selecting the entity in XCode, you then have an “Indexes” field in the inspector when you can set what looks to be a multi column index: “attribute1,attribute2”.

    I just tested it, and it does work, so multi column index IS supported since iOS5
