Json results to a string array in swift

Question

Hello i've been trying to make a json request and some of its results i want to put it to an array of string.

So i have the following code

var arrRes = [[String:AnyObject]]()
var nameaRR = [String]()
override func viewDidLoad() {
    super.viewDidLoad()

    Alamofire.request(.GET, "https://graph.facebook.com/search", parameters: ["q": "", "type": "place", "center": "37.928319,23.7036673", "distance": "10000","limit": "1000", "access_token": "SomeToken", "expires_in": "5184000"])
        .responseJSON { (responseData) -> Void in
            if((responseData.result.value) != nil) {
                let swiftyJsonVar = JSON(responseData.result.value!)
                //print(swiftyJsonVar)
                if let resData = swiftyJsonVar["data"].arrayObject {
                    self.arrRes = resData as! [[String:AnyObject]]


                    self.nameaRR = swiftyJsonVar["data"]["name"] as! [String]

                    print(self.nameaRR)

                }
                if self.arrRes.count > 0 {
                    self.kati.reloadData()
                }
            }

    }


}

The JSON Resul is the following

    {
      "data" : [
        {
          "category_list" : [
            {
              "id" : "272705352802676",
              "name" : "Outdoors"
            },
            {
              "id" : "115725465228008",
              "name" : "Region"
            }
          ],
          "id" : "552889064768971",
          "name" : "Παλαιο Φαληρο", //This String i want to put in an Array
          "category" : "Local business",
          "location" : {
            "street" : "",
            "city" : "Palaión Fáliron",
            "country" : "Greece",
            "longitude" : 23.6944070162,
            "zip" : "17562",
            "latitude" : 37.9284637008,
            "state" : ""
          }
        }
]
}

I get a warning
Cast from 'JSON' to unrelated type '[String]' always fails

But i'm stuck of how can i put all the Strngs to the array nameaRR. Can anyone help me find my mistake? Thanks!

Since you have already dereferenced resData why don't you keep using it rather than reuse swiftyJsonVar?? And name isn't an array. It's always String — vadian

There are quite a few problems with this code... The most obvious are: 1. swiftyJsonVar["data"] is an array so ["data"]["name"] is invalid (what you probably mean is to get the first item of the array and then grab the name) & 2. Even after name is retrieved it is just a String and not an array of strings ([String]), which means it cannot be assigned to nameaRR. I hope that this makes sense... — Alladinian

look do like that

if let resData = swiftyJsonVar["data"] as? [[String:AnyObject]] {
  if let categorylist = resData["category_list"] as? [[String:AnyObject]]{
    if let id =  categorylist["id"] as? Int{
   print(id)
}
} 
}
