Using different libraries in swift might be tricky, but here we combined a complete example for you SwiftyJSON SwiftyUserDefaults Alamofire How to request and parse request

1- create a model

class Package : NSObject, NSCoding, Mappable, DefaultsSerializable{

    var name: String?
    var desc: String?
    var cost: Int?
    var credit: Int?
    var days: Int?

}

class Package : NSObject, NSCoding, Mappable, DefaultsSerializable{

var name: String?

var desc: String?

var cost: Int?

var credit: Int?

var days: Int?

}

2- create a model init

    var _description: String {
        return "<name=\(name!)"
            + ", desc=\(desc!)"
            + ", cost=\(cost!)"
            + ", credit=\(credit!)"
            + ", days=\(days!)"
    }


    init(json: JSON) {

        
        self.name = json["name"].string ?? ""
        self.desc = json["desc"].string ?? ""
        self.cost = json["cost"].int
        self.credit = json["credit"].int
        self.days = json["days"].int

}

var _description: String {

return "<name=\(name!)"

+ ", desc=\(desc!)"

+ ", cost=\(cost!)"

+ ", credit=\(credit!)"

+ ", days=\(days!)"

}

init(json: JSON) {

self.name = json["name"].string ?? ""

self.desc = json["desc"].string ?? ""

self.cost = json["cost"].int

self.credit = json["credit"].int

self.days = json["days"].int

}

3- create a parse model method

   fileprivate func parse(packagesJSON: JSON) -> [Package] {
        var packages = [Package]()
        for (key: _, packageJSON: JSON) in packagesJSON {
            packages.append(Package(json: JSON))
        }
        return packages
    }

fileprivate func parse(packagesJSON: JSON) -> [Package] {

var packages = [Package]()

for (key: _, packageJSON: JSON) in packagesJSON {

packages.append(Package(json: JSON))

}

return packages

}

4- call and parse the json

        let headers: HTTPHeaders = [
         GlobalConstants.ApiKey: GlobalConstants.ApiKeyValue,
          "Accept": "application/json"
        ]
        
        Alamofire.request("https://example.com/configurations", parameters: ["show":"countries"], headers: headers)
                      .validate(statusCode: 200..<300)
                      .validate(contentType: ["application/json"])
                      .responseJSON { response in
                          print("Request: \(String(describing: response.request))")   // original url request
                          print("Response: \(String(describing: response.response))") // http url response
                          print("Result: \(response.result)")                         // response serialization result

                          if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
                             // print("Data: \(utf8Text)") // original server data as UTF8 string
                              do{
                                   // Get json data
                                  let json = try JSON(data: data)
                                //packages
                                
                          
                                 let packages = self.parse(packagesJSON: json["packages"])
                                for p in packages {
                                    print(p._description)
                                }
                                
                                /*
                                // Loop sub-json array
                                for (_, subJson) in json["packages"] {
                                // Display country name

                                                                print("name: \(name)");
                                                                  }
                                    if let description = subJson["description"].string {
                                                                print("description: \(description)")
                                                                  }

5- you might use these packages inside the Swifty User Default

                                 let _packages = self.parse(packagesJSON: json["packages"])
                                 let packages = DefaultsKey<[Package]?>("packages")
                                 Defaults[key: packages] = _packages
                                for p in Defaults[key: packages]! {
                                    print(p._description)
                                }

let _packages = self.parse(packagesJSON: json["packages"])

let packages = DefaultsKey<[Package]?>("packages")

Defaults[key: packages] = _packages

for p in Defaults[key: packages]! {

print(p._description)

}
