Swift parsing data from POST request

Question

This should be pretty simple but it's doing my head in. I'm doing a post request with swift and I get some Json data back:

Optional({
authString = "bWF0dEB0YXN0";
data =     {
    x = asd;
    y = 1234;
};
success = 1;
})

I can successfully get authString and success but I can't seem to be able to parse data

this works:

let auth = parseJSON["authString"] as? String

This doesn't:

let dataArray = parseJSON["data"] as? NSDictionary
println(dataArray["x"])

This returns nil:

let dataArray = parseJSON["data"] as? Array<NSDictionary>
println(dataArray)

Answer 1

Try:

let dataArray = parseJSON["data"] as? NSDictionary
println(dataArray?["x"])
//               ^ HERE

Because dataArray is Optional<NSDictionary> , you have to use "Optional Chaining" syntax.
