Updated answer

Try to do like this:

class MyViewController: UIViewController {
    fileprivate let viewList: [String] = ["Fixed", "Recurring"]
}

// MARK: - UIPickerViewDelegate
extension MyViewController: UIPickerViewDelegate {
    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
            print("Selected value \(viewList[row]) at row \(row)")

            if viewList[row] == "Fixed" {
                print("Fixed has been selected!")
            }
    }
}

The problem come from your condition, try the code below.
