Parsing JSON Response with Alamofire in Swift - ios

Question

When using the Alamofire Framework, my responses don't seem to be getting parsed correctly. The JSON response I get has some keys that appear to not be strings, and I don't know how to reference them/get their values.
Here is the part of my code that makes the call:
var url = "http://api.sandbox.amadeus.com/v1.2/flights/low-fare-search"
var params = ["origin": "IST",
"destination":"BOS",
"departure_date":"2014-10-15",
"number_of_results": 1,
"apikey": KEY]
Alamofire.request(.GET, url, parameters: params)
.responseJSON { (_, _, json, _) in
println(json)
}
}
And here is the first section printout when that function is called
Optional({
currency = USD;
results = ({
fare = {
"price_per_adult" = {
tax = "245.43";
"total_fare" = "721.43";
};
restrictions = {
"change_penalties" = 1;
refundable = 0;
};
"total_price" = "721.43";
};
...
});
});
You'll notice that results is not "results", but "price_per_adult" is the correct format. Is there some step I'm missing? When I cast it to NSDictionary it doesn't do anything to help the key format either.
I also tried the same endpoint in javascript and ruby, and both came back without problem, so I'm fairly confident that it is not the API that is causing problems.

Those keys are still Strings, that's just how Dictionarys are printlnd. It looks like it will surround the String in quotes when printing it only if it contains non-alphanumeric characters (_ in this case). You can test this by manually creating a Dictionary similar to the one you're getting back from your API request and then printing it:
let test = [
"currency": "USD",
"results": [
[
"fare": [
"price_per_adult": [
"tax": "245.43",
"total_fare": "721.43"
],
"restrictions": [
"change_penalties": 1,
"refundable": 0
],
"total_price": "721.43"
]
]
]
]
println(test)
Outputs:
{
currency = USD;
results = (
{
fare = {
"price_per_adult" = {
tax = "245.43";
"total_fare" = "721.43";
};
restrictions = {
"change_penalties" = 1;
refundable = 0;
};
"total_price" = "721.43";
};
}
);
}
