struct MyClass :Codable 
{ 
    var Status: String 
}

let session = URLSession.shared session.dataTask(with: request) { (data, response, error) in 
    do { let countries=try JSONDecoder().decode(MyClass.self, from : data!) 
        print(countries.Status)  
    } 
    catch { 
       print ("error"); 
    } 
}.resume()

попробуйте это: (я рекомендую использовать этот сайт: https://app.quicktype.io/)

// This file was generated from JSON Schema using quicktype, do not modify it directly.
// To parse the JSON, add this file to your project and do:
//
// let welcome = try? newJSONDecoder().decode(Welcome.self, from: jsonData)


import Foundation

// MARK: - WelcomeElement
struct WelcomeElement: Codable {
    let active: String
    let billingProperty: JSONNull?
    let das, entity, gulcoCode, inactive: String
    let lcoCode, lcoCategory, status, success: String
    let total, alcrights, freshActivation, profileexist: String
    let promorights: String
    let staffID: JSONNull?
    let userID: String
    let walletBalance: Double

    enum CodingKeys: String, CodingKey {
        case active = "Active"
        case billingProperty = "BillingProperty"
        case das = "DAS"
        case entity = "Entity"
        case gulcoCode = "GULCOCode"
        case inactive = "Inactive"
        case lcoCode = "LCOCode"
        case lcoCategory = "LcoCategory"
        case status = "Status"
        case success = "Success"
        case total = "Total"
        case alcrights, freshActivation, profileexist, promorights, staffID, userID, walletBalance
    }
}

typealias Welcome = [WelcomeElement]

// MARK: - Encode/decode helpers

class JSONNull: Codable, Hashable {

    public static func == (lhs: JSONNull, rhs: JSONNull) -> Bool {
        return true
    }

    public var hashValue: Int {
        return 0
    }

    public init() {}

    public required init(from decoder: Decoder) throws {
        let container = try decoder.singleValueContainer()
        if !container.decodeNil() {
            throw DecodingError.typeMismatch(JSONNull.self, DecodingError.Context(codingPath: decoder.codingPath, debugDescription: "Wrong type for JSONNull"))
        }
    }

    public func encode(to encoder: Encoder) throws {
        var container = encoder.singleValueContainer()
        try container.encodeNil()
    }
}
