Answer 1

func animateToUserLocation() {
    if let annoation = mapView.annotations.filter ({ $0 is MKUserLocation }).first {
        let coordinate = annoation.coordinate
        let viewRegion = MKCoordinateRegion(center: coordinate, latitudinalMeters: 200, longitudinalMeters: 200)
        mapView.setRegion(viewRegion, animated: true)
    }
}
