Ошибка строкового символа Swift 2 Json utf8

У меня работает Json файл и приложение, но у меня есть текст encoding проблема.

мой Json пример вывода файла

{"status":"SUCCESS","data":[{"id":"21","title":"I'm working on project","description":"Lorem ipsum dolor sit er elit lamet, consectetaur cilliim adipisicin"}]}

Json Функции разбора, я добавил парсинг некоторых функций, которые вы можете увидеть под

    func initArrayCategory(){
self.getResponseFromURL(self.getStringURLWithJSONFormatForUserAPI(URL_API_NEWS_CATEGORIES), withParams: nil, Success: { (operation, responseObject) -> () in

if let data = responseObject[API_PARAM_DATA] as? NSMutableArray{
self.arrayCategory = data
}
}

Контроллер моего вида

class ViewController: UIViewController {


var detailTitle:String?
var detailDesc:String?

@IBOutlet weak var textim: UILabel!
@IBOutlet weak var textbig: UITextView!

override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {

required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}

override func viewDidLoad() {
super.viewDidLoad()

textbig.text = detailDesc
textim.text = detailTitle


}

Mysql Table Mysql файл

Mysql Real Value из таблицы

Удаленное подключение Php файл

$db_host="my host";   // your mysql database host name
$db_username="myusername";  // username
$db_pass="my past";                 // password
$connnect=mysql_connect("$db_host","$db_username","$db_pass") or die("Databese Error, Please check your connection values !");
@mysql_select_db ("App");  // Select Your Database


@mysql_query("SET NAMES utf8");
@mysql_query("SET CHARACTER SET utf8");
@mysql_query("SET COLLATION_CONNECTION = 'utf8_general_ci'");

Дистанционный пульт Php файл

header("Content-type: application/json; charset=utf-8");
include("connect.php");

$q = "Select * from App";
$r = mysql_query($q) or die(mysql_error());

if(mysql_num_rows($r) > 0) {

$arr = array();

while ($row = mysql_fetch_assoc($r))
{
$arr[] = $row;
}
echo json_encode(array('status'=>"SUCCESS",'data'=>$arr));
}
else {
echo json_encode(array('status'=>"FAIL"));
}

Выход

textim.text =  I'm working on project

должно быть

textim.text = I'm working on project

json file coming title = I'm working on project

пожалуйста, помогите мне
