Getting initializer error on ViewController

Question

I get the error: "Class 'ViewController' has no initializer". I have narrowed down the problem to this function that is being called. Does anyone see the problem?

let locationManager1: CLLocationManager // your location manager
    func addBoundry(loc: CLLocation)
    {
        if let loc: CLLocation! = locationManager1.location {
        let center: CLLocationCoordinate2D = loc!.coordinate
        let lat: CLLocationDegrees = center.latitude
        let long: CLLocationDegrees = center.longitude
        var points = [CLLocationCoordinate2DMake(lat,long),CLLocationCoordinate2DMake(lat,long),CLLocationCoordinate2DMake(lat,long),CLLocationCoordinate2DMake(lat,long)]
        let polygon = MKPolygon(coordinates: &points, count: points.count)

        mapView.addOverlay(polygon)

        } else {
            print("no location...")
        }
    }

When you say let locationManager1: CLLocationManager, you're declaring a property that must not be nil, but not actually assigning anything to it.

So, you either need to declare an init that ensures locationManager1 is assigned exactly one value (it's a let constant, not a var, after all!) or initialize the property inline like:

let locationManager1 = CLLocationManager()
