JSON with variable dates in SwiftyJson for iOS

Question

I want to parse a json with variable keys. Here is the example:

"Time Series (Daily)": {
        "2018-09-14": {
            "1. open": "113.3600",
            "2. high": "113.7300",
            "3. low": "112.4400",
            "4. close": "113.3700",
            "5. adjusted close": "113.3700",
            "6. volume": "19122349",
            "7. dividend amount": "0.0000",
            "8. split coefficient": "1.0000"
        },
        "2018-09-13": {
            "1. open": "112.1200",
            "2. high": "113.7250",
            "3. low": "112.1200",
            "4. close": "112.9100",
            "5. adjusted close": "112.9100",
            "6. volume": "26055620",
            "7. dividend amount": "0.0000",
            "8. split coefficient": "1.0000"
        },
        "2018-09-12": {
            "1. open": "111.4300",
            "2. high": "111.8500",
            "3. low": "110.5100",
            "4. close": "111.7100",
            "5. adjusted close": "111.7100",
            "6. volume": "18891064",
            "7. dividend amount": "0.0000",
            "8. split coefficient": "1.0000"
        }
        ...
    }

Using SwiftyJSON i know how to convert a JSON with static keys. But i am not aware of any way to take date (2018-09-13 etc) as a Data Bean and create an Array of dates. What is the best way to handle this scenario?

The code i use for parsing the static keys in SwiftJSON is:

func get<T>(url: String, queryParams: Parameters!, onComplete: @escaping (T?, Error?) -> ()) where T : Codable {
        URLCache.shared.removeAllCachedResponses()
        Alamofire.request(url, method: .get, parameters: queryParams, encoding: URLEncoding.default, headers: self.headers!).responseString {
            response in
            print("URL: \(url)")

            switch response.result {
            case .success(let value):
                let statusCode = response.response?.statusCode
                if (statusCode == Constant.httpSuccessCode){
                    print("Value: \(value)")
                    let json: String = JSON(value).string!
                    let jsonObj : T! = StringManager.decode(stringRepresentation: json)
                    onComplete(jsonObj, nil)
                }else if(statusCode == Constant.httpInternalServerErrorCode){
                   //Error handling
                }else if(statusCode == Constant.httpForbiddenCode || statusCode == Constant.httpUnAuthorizedCode){
                   //error handling
                }else {
                   //error handling
                }

            case .failure(let error):
               //error handling
            }
            //response is the json.
        }
    }

Answer 1

json's root is a JsonObject i.e. Key and Value Date is the key and value is again a JsonObject. So it can be handled like

Code

import SwiftyJSON
class Test{

    let s = """

    {"Time Series (Daily)": {
        "2018-09-14": {
            "1. open": "113.3600",
            "2. high": "113.7300",
            "3. low": "112.4400",
            "4. close": "113.3700",
            "5. adjusted close": "113.3700",
            "6. volume": "19122349",
            "7. dividend amount": "0.0000",
            "8. split coefficient": "1.0000"
        },
        "2018-09-13": {
            "1. open": "112.1200",
            "2. high": "113.7250",
            "3. low": "112.1200",
            "4. close": "112.9100",
            "5. adjusted close": "112.9100",
            "6. volume": "26055620",
            "7. dividend amount": "0.0000",
            "8. split coefficient": "1.0000"
        },
        "2018-09-12": {
            "1. open": "111.4300",
            "2. high": "111.8500",
            "3. low": "110.5100",
            "4. close": "111.7100",
            "5. adjusted close": "111.7100",
            "6. volume": "18891064",
            "7. dividend amount": "0.0000",
            "8. split coefficient": "1.0000"
        }
    }
    }
    """
    func parseJSON(){

        let j = JSON(parseJSON: s)
        let timeSeries = j["Time Series (Daily)"]
        for (key,json) in timeSeries{
            print("\(key):")
            json.forEach({
            print("\($0) : \($1)")
        })
        }

    }

}

output

   2018-09-14:
1. open : 113.3600
4. close : 113.3700
8. split coefficient : 1.0000
