Why is SwifyJSON dictionaryValue empty? - json

Question

I'm using SwifyJSON to parse some JSON sent to my iOS app through socket.io and the .dictionaryValue of the response is nil. Here's how the data is sent from the server:
socket.emit('hasBeenMatched', {user: JSON.stringify(currentUser)});
Here's what I've got in my iOS app:
socket.on("hasBeenMatched", callback: {data, ack in
println("got response after requesting match");
let user = JSON(data!)
println(user)
println(user[0])
println(user[0]["user"])
println(user[0]["user"].dictionaryValue)
})
And here's the output of that code:
got response after requesting match
[
{
"user" : "{\"_id\":\"5511c3d8abcdc2fcf7b8fe4b\",\"email\":\"j\",\"password\":null,\"firstname\":\"j\",\"lastname\":\"j\",\"age\":9,\"radius\":\"9\",\"__v\":0,\"wantsToBeMatched\":true,\"matchedWith\":\"k k\"}"
}
]
{
"user" : "{\"_id\":\"5511c3d8abcdc2fcf7b8fe4b\",\"email\":\"j\",\"password\":null,\"firstname\":\"j\",\"lastname\":\"j\",\"age\":9,\"radius\":\"9\",\"__v\":0,\"wantsToBeMatched\":true,\"matchedWith\":\"k k\"}"
}
{"_id":"5511c3d8abcdc2fcf7b8fe4b","email":"j","password":null,"firstname":"j","lastname":"j","age":9,"radius":"9","__v":0,"wantsToBeMatched":true,"matchedWith":"k k"}
[:]
In an alternate part of my code I have the following code:
let request = Alamofire.request(.POST, "http://localhost:3000/api/users/authenticate", parameters: params)
request.validate()
request.response { [weak self] request, response, data, error in
if let strongSelf = self {
// Handle various error cases here....
var serializationError: NSError?
if let json: AnyObject = NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments, error: &serializationError) {
println(JSON(json).dictionaryValue)
// Story board navigation
} else {
//Handle error case
}
}
}
EDIT: the output of the println in the Alamofire response handling looks like:
[_id: 5511c3d8abcdc2fcf7b8fe4b, password: null, __v: 0, lastname: j, age: 9, wantsToBeMatched: true, firstname: j, radius: 9, email: j, matchedWith: k k]
What I'm wondering is: why does println(user[0]["user"].dictionaryValue) result in [:]?

Answer 1

Figured it out, but my solution isn't related to SwiftyJSON (which I'm still curious about). I changed how my server sends data over socket. I changed socket.emit('hasBeenMatched', {user: JSON.stringify(currentUser)}); to socket.emit('hasBeenMatched', {user: currentUser});. Essentially, I removed the manual JSON-ification.
