Geofence Region複数設定？

Geofence Region複数設定したい。(20箇所)
CLCircularRegion.identifier別に通知を配信したい。```class ViewController: UIViewController, CLLocationManagerDelegate {
var audioPlayerInstance : AVAudioPlayer! = nil
@IBOutlet weak var myimage: UIImageView!
let locationManager: CLLocationManager = CLLocationManager()

override func viewDidLoad() {
super.viewDidLoad()
self.myimage.isHidden = true
locationManager.delegate = self
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
locationManager.distanceFilter = 10

let geoFenceRegion:CLCircularRegion = CLCircularRegion(center: CLLocationCoordinate2DMake(33.654237, 130.693872),radius: 500.0,identifier: "TokyoTower")
locationManager.startMonitoring(for: geoFenceRegion)

let soundFilePath = Bundle.main.path(forResource: "new", ofType: "mp3")!
let sound:URL = URL(fileURLWithPath: soundFilePath)
// AVAudioPlayerのインスタンスを作成
do {
audioPlayerInstance = try AVAudioPlayer(contentsOf: sound, fileTypeHint:nil)
} catch {
print("AVAudioPlayerインスタンス作成失敗")
}
// バッファに保持していつでも再生できるようにする
audioPlayerInstance.prepareToPlay()
audioPlayerInstance.volume = 2

UNUserNotificationCenter.current().requestAuthorization(options: [.alert,.badge,.sound], completionHandler: {(success,error) in
if error != nil{
print("失敗しました")
}

}
})
}

func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) {

audioPlayerInstance.play()

timedNotifications(inSeconds: 3) {(success) in
