如何访问不同目标的类实例？

Question

I'm using Notification ContentExtension which is in the different target from the main target.

I want to access and call the method of AppDelegate located in the main target from the different target.

Is this possible? I tried with notification-observer pattern but it doesn't seem to reach to main target's instance. It seems like they are working separately.

NOTE: I'm NOT asking a way to share a file in different targets.

MMWormhole is a great tool to do just this. It's just like NotificationCenter but with the added benefit that the notifications can cross from an extensions target back to the main app's target.

(there are plenty of examples in the README for the project)
