Json results to a string array in swift

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!

Answer

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)
}
} 
}
