How to know notConnected Internet state with ErrorResponse of Alamofire

You can access URLError by error.asAFError?.underlyingError

enum ErrorType: Equatable {
    case networkError
    case serverError(_ error: ServerError)
    case unknownError(_ error: Error)

    init(error: Error) {
        if let errorResponse = error as? ErrorResponse {
            switch errorResponse {
            case .error(let statusCode, let data, let error):
                if let urlError = error.asAFError?.underlyingError as? URLError,
                   urlError.code == URLError.Code.notConnectedToInternet
                {
                    self = .networkError
                } else {
                    self = .serverError(ServerError(statusCode: statusCode, data: data))
                }
            }
        } else {
        self = .unknownError(error)
        }
    }
