How to use enum to get string value

Question

Actually I'm trying to Populate API JSON data to tableView but I cannot use enum as a string.

struct Results: Codable {
    let container_id : Int?
    let container_number : String?
    let shipment_id : Int?
    let bill_of_lading : BillOfLading
    let eta : String?
    let discharge_port_id : Int?
    let discharge_port_name : String?
    let consignee_id : Int?
    let consignee_name : String?
    let customer_id : Int?
    let customer_name : String?
    let shipment_status : String?
    let container_status : String?
    let user_id : Int?
    let user_display_name : String?
    let commodities : [Commodities]
    let all_sold : Bool?
    let quantities : Quantities
    let sales : [String]?
    let sales_report : Sales_report
    let commodities_summary : String?
    let commodity_quantity_summary : String?
    let commodities_summary_en : String?
    let commodity_quantity_summary_en : String?
}

enum BillOfLading: Codable {
    case integer(Int)
    case string(String)

    init(from decoder: Decoder) throws {
        let container = try decoder.singleValueContainer()
        if let x = try? container.decode(Int.self) {
            self = .integer(x)
            return
        }
        if let x = try? container.decode(String.self) {
            self = .string(x)
            return
        }
        throw DecodingError.typeMismatch(BillOfLading.self, DecodingError.Context(codingPath: decoder.codingPath, debugDescription: "Wrong type for BillOfLading"))
    }

    func encode(to encoder: Encoder) throws {
        var container = encoder.singleValueContainer()
        switch self {
        case .integer(let x):
            try container.encode(x)
        case .string(let x):
            try container.encode(x)
        }
    }
}

You can define a computed property, e.g.

extension BillOfLading {
    var stringValue: String {
        switch self {
            case .integer(let value): return String(value)
            case .string(let value): return value
        }
    }
}

Then you can do

cell.bolLabel.text = data.bill_of_lading.stringValue
