You must mark the window and testNavigationController variables as optional:

var window : UIWindow?
var testNavigationController : UINavigationController?

Swift classes require non-optional properties to be initialized during the instantiation:

Classes and structures must set all of their stored properties to an appropriate initial value by the time an instance of that class or structure is created. Stored properties cannot be left in an indeterminate state.

Properties of optional type are automatically initialized with a value of nil, indicating that the property is deliberately intended to have “no value yet” during initialization.

When using optional variables, remember to unwrap them with !, such as:

self.window!.backgroundColor = UIColor.whiteColor();
