Not sure about you guys, but I'm having a hard time with this one. I did something like this:

if let window = UIApplication.shared.delegate?.window {
    if var viewController = window?.rootViewController {
        // handle navigation controllers
        if(viewController is UINavigationController){
            viewController = (viewController as! UINavigationController).visibleViewController!
        }
        print(viewController)
    }
}

I kept getting the initial view controller of my app. For some reason it wanted to stay the root view controller no matter what. So I just made a global string type variable currentViewController and set its value myself in each viewDidLoad(). All I needed was to tell which screen I was on & this works perfectly for me.
