Use AppDelegate in today extension

Question

I'm trying to build an today extension for my app.

I'm using CoreData and NSFetchedResultsController and get the following error:

Use of undeclared type 'AppDelegate'

In this line of code:

var appDel: AppDelegate = UIApplication.sharedApplication().delegate as AppDelegate. 

Does someone know how to solve this error / use AppDelegate in the today extension and would like to help me?

A Today Extension isn't an application, so UIApplication and AppDelegate aren't available. I'm not for sure what you are trying to do with the AppDelegate, but extensions do have a NSExtensionContext available by calling:

 self.extensionContext
