如何在我的Swift应用程序的其他位置使用locationManager函数中的经度值和纬度值

class LocationManager {
    static let shared = LocationManager()
    
    var latitude: Double?
    var longitude: Double?
    
    private init() {}
}

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    guard let location = locations.last else { return }
    
    LocationManager.shared.latitude = location.coordinate.latitude
    LocationManager.shared.longitude = location.coordinate.longitude
}

if let latitude = LocationManager.shared.latitude, let longitude = LocationManager.shared.longitude {
    // 在这里使用经度和纬度值进行其他操作
} else {
    // 经度和纬度值尚未被设置
}
