iOS15 LocationButton

#エラー発生

• iOS15から導入された「LocationButton」普通に書くと
  [Error Domain=kCLErrorDomain Code=1 "(null)]
  が出る
  結局、「requestLocationAuth()」とPlistへのお約束が必要だった（XCode13にはデフォルトないけど）
  確認するには「stopLocation()」で一回update Locationを止めて確認する

LocationButton

class LocationButtonViewModel: NSObject, ObservableObject, CLLocationManagerDelegate {
//その他省略
    func requestLocation() {
        locationManager.requestLocation()
    }
    func stopLocation() {
        locationManager.stopUpdatingLocation()
    }

     func requestLocationAuth(man: CLLocationManager) {

        locationManager.requestAlwaysAuthorization()
        locationManager.desiredAccuracy = kCLLocationAccuracyReduced

        switch man.authorizationStatus {
        case .authorizedAlways:
            locationStatus = "authorized always"
            checkLocationAccuracyAllowed()
        case .authorizedWhenInUse:
            locationStatus = "authorized when in use"
            checkLocationAccuracyAllowed()

        var body: some View {
 
        LocationButton(.currentLocation) {
            locationVM.requestLocation()
        }
