Today I converted my old code base to swift 3 and xCode did everything but there are few things that I am not able to understand.

Old swift:

private var fetchedResultController: NSFetchedResultsController?

Swift 3:

fileprivate var fetchedResultController: NSFetchedResultsController<AnyObject>?

Now the problem is when I simply write the previous one xCode throw an error Reference to generic type NSFetchedResultsController requires arguments in <....>

and it's turned to NSFetchedResultsController<AnyObject>? but still it's showing me an error which I am not able to figure.

Can anyone please help to understand what exactly it mean? and how to figure out?

Compare http://stackoverflow.com/questions/39517493/nsfetchedresultscontroller-deletecache-in-swift-3 for a similar issue. `NSFetchedResultsController` or `NSFetchedResultsController` should work. – Martin R Sep 15 '16 at 20:28
May be you are right but still I can't solve and understand it either. – Tapas Pal Sep 15 '16 at 20:34
Did you try what I suggested? – Martin R Sep 15 '16 at 20:43
I tried `NSFetchedResultsController` and it's showing the same error. – Tapas Pal Sep 16 '16 at 09:27
Please update the *question* with your code. – Martin R Sep 16 '16 at 09:28
@MartinR I did the same as you have suggested. First time it was not worked. I just clean the project and it's started working. :) – Tapas Pal Sep 20 '16 at 11:40
