iOS Question

Type 'AnyObject' does not conform to protocol 'NSFetchRequestResult'

I just installed

Xcode 8 beta 2
iOS 10 beta
. I have an existing project where I updated from swift 2.3 to swift 3 based on a prompt from Xcode. I received an error with my code data code.

This was auto generated in the conversion from swift 2.3 to swift 3 by xcode

var fetchedResultsController: NSFetchedResultsController<AnyObject>!

the error I'm receiving is

Type 'AnyObject' does not conform to protocol 'NSFetchRequestResult'

I tried to conform AnyObject

extension AnyObject: NSFetchRequestResult {}

But I receive another error

enter image description here

I am not sure what I need to do or if my fetchedResultsController needs to be changed in the first place.

var fetchedResultsController: NSFetchedResultsController<Content>!

The Xcode converter likely was confused about what Entity you wanted to return in this fetched results controller. Replace AnyObject with the entity type you are fetching.

You should open a radar ( on this, since it should never suggest AnyObject here. At worst it should suggest NSManagedObject.
