title: The data couldn’t be read because it isn’t in the correct format [swift 3]
body: <p>I've json data that have json string(value) that that look like this</p>
  
  <pre><code>{
       "Label" : "NY Home1",
       "Value" : "{\"state\":\"NY\",\"city\":\"NY\",\"postalCode\":\"22002\",\"value\":\"Fifth Avenue1\nNY NY 22002\nUSA\",\"iosIdentifier\":\"71395A78-604F-47BE-BC3C-7F932263D397\",\"street\":\"Fifth Avenue1\",\"country\":\"USA\"}",
  }
  </code></pre>
  
  <p>I take the jsonString using swiftyjson</p>
  
  <pre><code>let value = sub["Value"].string ?? ""
  </code></pre>
  
  <p>After that I convert this jsonString to Dictionary with this below code but it always show this error message <code>The data couldn’t be read because it isn’t in the correct format</code></p>
  
  <pre><code>if let data = value.data(using: String.Encoding.utf8) {
          do {
              let a = try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]
              print("check \(a)")
          } catch {
              print("ERROR \(error.localizedDescription)")
          }
      }
  </code></pre>
  
  <p>I think this happen because "\n", how to convert jsonstring to dictionary that have "\n" ?</p>
