I want to make Location Base AR in Swift 3.0, ARkit - ios

Question

I'm japanese and I'm a beginner. This is first time that i post to stackoverflow.
Now, I am trying to make location base AR app, that specific objects appear in specific position, using ARkit and CoreLocation.
For example, sphere3Node appear in latitude > 35.5 (refer in my source code).
This code is working successfully, but sphere3Node cannot appear in screen.
import SceneKit
import ARKit
import CoreLocation
import UIKit
class ViewController: UIViewController, ARSCNViewDelegate, CLLocationManagerDelegate{
var locationManager = CLLocationManager()
var locationData : CLLocation? = nil
#IBOutlet weak var idoLabel: UILabel!
#IBOutlet weak var keidoLabel: UILabel!
#IBOutlet weak var hyoukouLabel: UILabel!
#IBOutlet weak var hanteiLabel: UILabel!
private let label: UILabel = UILabel()
