Swift 3/ Xcode 8 here:

func addRadiusCircle(location: CLLocation){
    if let poll = self.selectedPoll {
        self.mapView.delegate = self
        let circle = MKCircle(center: location.coordinate, radius: 10)
        self.mapView.add(circle)
    }
}

func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
    if overlay is MKCircle {
        let circle = MKCircleRenderer(overlay: overlay)
        circle.strokeColor = UIColor.red
        circle.fillColor = UIColor(red: 255, green: 0, blue: 0, alpha: 0.1)
        circle.lineWidth = 1
        return circle
    } else {
        return MKPolylineRenderer()
    }
}

Then call like so:

self.addRadiusCircle(location: CLLocation(latitude: YOUR_LAT_HERE, longitude: YOUR_LNG_HERE))
