I'm trying to retrieve the data from an API request, however, I'm having trouble parsing some of the nested parts of the JSON data.

The JSON structure looks like this:

Code Block ["quoteResponse": {
  error = "<null>";
  result =   (
        {
      ask = "607.65";
      gmtOffSetMilliseconds = "-18000000";
      language = "en-US";
      longName = "Tesla, Inc.";
      market = "us_market";
    }
  );
}]

And I am trying to retrieve language, market, ask, etc. from this API response. The problem is, I am having trouble casting result as a dictionary.

Code Block Swiftif let dictionary = jsonData as? [String: Any] { print(dictionary) if let nestedDictionary = dictionary["quoteResponse"] as? [String: Any] { if let results = nestedDictionary["result"] as? Any{ print(results) } } }

I cannot convert it to a string nor can I turn it into a usable array. How do I access these values?

The snippet you posted is not valid JSON; specifically, the outer element in an array (denoted by square brackets) but it contains a key-value pair like a dictionary. If you can post a valid snippet, we should be able to advise you further.

Unfortunately, serializing the data as JSON yields this incorrect JSON structure.

Doing:

Code Block swiftjsonData = try? JSONSerialization.jsonObject(with: data!, options: [])

with the data retrieved from the API request yields this incorrect structure. However, encoding the data as a string yields the correct JSON structure. However, converting that string back to JSON results in the same problem.

How do I fix this?

Unfortunately, serializing the data as JSON yields this incorrect JSON
structure.

So where does this data originate from?
