【Swift】CoreLocationで現在地取得

CoreLocationを使って現在地の緯度経度を一瞬取得するためのextensionです。

ViewController.swift

import CoreLocation

Viewcontroller.swift

override func viewDidLoad() {
        super.viewDidLoad()

        //CLLocationManagerDelegateのセットアップ
        locationManager.delegate = self
        //位置情報使ってもいい？
        locationManager.requestWhenInUseAuthorization()
        
    }

Viewcontroller.swift

extension ViewController: CLLocationManagerDelegate {
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.last {
            
            locationManager.stopUpdatingLocation()
            var lat = location.coordinate.latitude
            var lon = location.coordinate.longitude
            //緯度・経度を渡す
            parseLocation(lat: lat, lon: lon)

        }
    }
    
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        print(error)
    }
    
    
}

Viewcontroller.swift

@IBAction func buttonPressed(_ sender: UIButton) {
        //位置情報の取得開始
        locationManager.startUpdatingLocation()
    }
