will be helpful for those in need You are passing an array in second case, but still you are casting it to NSDictionary
Change the following code:
code :
var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
var jsonResult: NSArray = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSArray

like below fixes the issue I've come across an interesting issue when trying to use a JSON feed generated by PHP/MySQL using PDO. By default, the result of a query e.g. SELECT COUNT(id) FROM table name is returned as a String, but when I do any mathematical calculations on the result e.g. $result = $result + 1; the result is the 'correct' datatype. , I think you can do somethink like
code :
let score = Int(jsonData["score"] as? String)

I hope this helps . You can represent newline symbols with escaped character \\n. Here's an example of decoding such string:
code :
struct Entity: Codable {
  var title: String
  var desc: String
}

let testJson = """
{
  "title": "Title",
  "desc": "first row,\\nsecond row,\\n\\nthird row"
}
"""
let testData = testJson.data(using: .utf8)!

do {
  let entity = try JSONDecoder().decode(Entity.self, from: testData)
  print(entity)
} catch {
  print(error)
}

Any of those help How to create a Json object like this , Using Codable you can define your struct like this
code :
struct Root: Codable {
    let child: [String: Int]
    let childAge: [String: [Int]]
}
let root = Root(child: ["0": 0, "1": 0], childAge: ["0": [0], "1": [0]])

let encoder = JSONEncoder()
encoder.keyEncodingStrategy = .convertToSnakeCase

do {
    let data = try encoder.encode(root)
    if let json = String(data: data, encoding: .utf8) {
        //...
    }
} catch {
    print(error)
}
