What is causing the error "cannot convert value of type 'CLLocation.Type' to expected argument type 'CLLocation'"

I am attempting to add location detection to an app and for the most part I have it figured out. But I am having issues with the reverseGeocodeLocation method. I am getting the error cannot convert value of type 'CLLocation.Type' to expected argument type 'CLLocation'. What would be causing this? Here is my code:

func loadLocation() {
    self.locationManager = CLLocationManager()
    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = 2000
    self.locationManager.startUpdatingLocation()
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

    self.locationManager.stopUpdatingLocation()
    var location = locations.first
    var geoCoder: CLGeocoder!

    geoCoder.reverseGeocodeLocation(location: CLLocation) { (placemarks: [CLPlacemark]?, error: NSError?) -> Void in
                                                    ^ Error Here
        var placemark: CLPlacemark = placemarks?.first
        self.location = placemark.locality
        self.location = placemark.administrativeArea
    }
}

locationManager and location are called above the viewDidLoad:

var locationManager: CLLocationManager!
var location: String!

override func viewDidLoad() {
    super.viewDidLoad()

    loadLocation()
    retrieveWeatherForecast()
}

If you find any other issues with my code you can point that out also.

Update:

After making the changes that trojanfoe suggested, this is what I have:

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

    self.locationManager.stopUpdatingLocation()
    let location = locations.first
    var geoCoder: CLGeocoder!

    geoCoder.reverseGeocodeLocation(location!) { (placemarks: [CLPlacemark]?, error: NSError?) -> Void in

        let placemark: CLPlacemark = (placemarks?.first)!
        self.location = placemark.locality
        self.location = placemark.administrativeArea
    }
}

Xcode wants me to change var geoCoder: CLGeocoder! to let geoCoder: CLGeocoder!. If I do, I get this error Variable 'geoCoder' captured by a closure before being initialized. What should I do?

CLLocation is the class (i.e. the type).

Don't you want to pass it one of the instances within the array that is passed to that method?

For example:

var location = locations.first
let geoCoder = CLGeocoder()
geoCoder.reverseGeocodeLocation(location: location) { ...
