//JSON example
{
  "ObjectList": [
    {
      "x": "Starbucks", 
      "y": "asd"
    }, 
    {
      "x": "Starbucks", 
      "y": "asd"
    }
  ]
}
//
	  
struct Object: Codable {
    var x: String
	var y: String
}

struct ObjecttList: Decodable {
    let objects : [Object]
}

var result:ObjecttList?

let jsonUrlString = "http://www.json-generator.com/api/json/get/cfpSCkOGjS?indent=2"

guard let url = URL(string: jsonUrlString) else {return}
URLSession.shared.dataTask(with: url) { (data, response, err) in
	guard let data = data else {return}
    	do {
                let articlesData = try JSONDecoder().decode(ObjecttList.self, from: data)
                DispatchQueue.main.async {
                    self.result = articlesData
                }
            } catch let jsonErr {
                print("Error serializing json", jsonErr)
            }
