Writing a Protocol in a swift Framework?

Question

Im trying to write a Swift framework with a protocol used for a delegate method. I've made the protocol public, but when I add my framework to my project, the project spits out the following error ViewController.swift:15:83: No type named 'MyControllerDelegate' in module 'MyModule'

import MyModule

class ViewController: UIViewController, MyModule.MyControllerDelegate {

Any help in these regards would be appreciated.

Update: not sure if this makes any difference but some of the object types in the protocol are defined by another framework...
