Here is @Deepak's answer in Swift 3 for iOS 10:

extension ViewController: MKMapViewDelegate
{
    func mapView( _ mapView: MKMapView, didUpdate userLocation: MKUserLocation )
    {
        let regionRadius = 400 // in meters
        let coordinateRegion = MKCoordinateRegionMakeWithDistance( userLocation.coordinate, regionRadius, regionRadius )
        self.mapView.setRegion( coordinateRegion, animated: true)
    }
}
