Only able to parse SOME of JSON data, syntax issue? - ios

Question

I'm having an issue parsing some of the JSON data being retrieved from Oxford Dictionaries into my application.
I am printing the JSON response into my console which confirms that I am successfully getting the data needed.
Verification that JSON data is being retrieved:
There are two main folders initially when I get the JSON data back. "results", which contains the information I need: the word definition and other information
and "metadata".
JSON format that I am getting back from Oxford Dictionary:
I am able to parse the information contained in the "metadata" folder, and have printed it into the console to confirm.
Verification that I am able to parse and print the metadata:
I however, can't seem to parse any of the data contained in the 'Results' folder, which is what I actually need. The definition, the language, the word ID, et cetera.
What am I doing wrong here??
Example of issue with parsing "results" data:
Another example of faulty attempt to parse 'results':

Answer 1

Retrieve results like this:
let results = json["results"][0]["id"]
Or
if let resultObj = json["results"].first {
let id = resultObj["id"]
}
id key is in the dictionary which is at zero index of results array.
