title: Cocoa Storyboard Responder Chain
body: <p>Storyboards for Cocoa apps seems like a great solution as I prefer the methodology you find in iOS. However, while breaking things up into separate view controllers makes a lot of logical sense, I'm not clear as to how to pass window control (toolbar buttons) or menu interaction down to the view controllers that care. My app delegate is the first responder and it receives the the menu or toolbar actions, however, how can I access the view controller that I need to get that message to? Can you just drill down into the view controllers hierarchy. If so, how do you get there from the app delegate since it's the first responder? Can you make the window controller the first responder instead. If so, how? In the storyboard? Where?</p>
  
  <p>Since this is a high level question it may not matter, however, I am using Swift for this project if you're wondering. </p>
