swift and sharedapplication

first post!

i've been working with swift for a while now, but decided to move some of my code to using shared variables and objects. I'm having a fundamental issue with being able to reference appDelegate.SharedApplication().delegate. Even with a basic test application (to see if I could see any fundamental problems), I cannot get a reference to the shared variable - 

 // AppDelegate.swift
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

let info: String = "test"
}

trying to add - "let ref = UIApplication.sharedApplication().delegate as appDelegate" in another class complains of use of undeclared type app delegate.

removing that cast allows that, but once I try to create another variable reference to the info string, complains of no member named ref.

this seems such an obvious and confusing issue that I thought it time to ask for an answer :) all i want is to be able to use the appdelegate for controlling cllocationmanager and storing the return data in a variable for a view controller class to refer to.

xcode 6.1.1

cheers

Maybe you are confusing the compiler because you are not using the proper case (upper or lower) when referring to variables or classes.

A class starts with an UpperCase letter.
Any variable starts with a lowerCase letter.

While this is not a rule for variables, it is a well-heeded convention.

Thus: 

let stringFromDelegate =
 (UIApplication.sharedApplication() as AppDelegate).info
