How to pass a value from a dictionary (which is inside another dictionary) to a Label? Swift 3

Question

I have a database something like this:

{
  "status": "OK",
  "data": [
    {
      "id": 1,
      "name": "Mike",
      "informations": [
        {
          "id": 474,
          "text": "My son",
          "reference": "www.google.com",
        }
      ]
    }

I’m looking for this data through the Alamofire. I would like to create a View, insert a Label and, in this Label, appear the text of the attribute "text" and in another Label, the name of the attribute "name" and another with the value "reference". What’s the best way to do that?

You need to cast your Any elements to the type of your element: Try as follows, if Voce has trouble Parsing your dictionary in one conditional, best break-down the code below:

let dict: [String: Any] = ["status": "OK", "data": [["id": 1, "name": "Mike", "informations": [[ "id": 474, "text": "My son", "reference": "www.google.com" ]]]]]

if let status = dict["status"] as? String, status == "OK",
    let data = dict["data"] as? [[String: Any]],
    let dataDict = data.first,
    let id = dataDict["id"] as? Int,
    let name = dataDict["name"] as? String,
    let info = dataDict["informations"] as? [[String: Any]],
    let infoDict = info.first,
    let infoID = infoDict["id"] as? Int,
    let text = infoDict["text"] as? String,
    let reference = infoDict["reference"] as? String {
    print(id)     // ""1\n"
    print(name)   // "Mike\n"
    print(infoID) // "474\n"
    print(text)   // "My son\n"
}
