Tableview works on sim but not on test device - swift

Question

I have no idea whats wrong with this function. I'm calling it in viewdidload and it prints the array as blank when I load it on my phone. When I do it in the simulator it fills the array though. Using ObjectMapper if that helps at all.
func getData() {
let myURLString = "http://meetup.x10host.com/api/get_event.php?radius=15"
let myURL = NSURL(string: myURLString)!
var myCardsArray = [Card]()
let mySession = NSURLSession(configuration: NSURLSessionConfiguration.defaultSessionConfiguration())
let myDataTask = mySession.dataTaskWithURL(myURL) { (data, response, error) in
guard error == nil else {
let alertController = UIAlertController(title: "No Connection", message:
"Can't connect to database, perhaps turn on your WiFi?", preferredStyle: UIAlertControllerStyle.Alert)
alertController.addAction(UIAlertAction(title: "Okay", style: UIAlertActionStyle.Default,handler: nil))
self.presentViewController(alertController, animated: true, completion: nil)
return
}
do {
let jsonData = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.AllowFragments)
for someCard in jsonData as! NSArray{
let card = Mapper<Card>().map(someCard)
myCardsArray.append(card!)
self.nameArray.append(card!.titlee!)
self.textArray.append(card!.text!)
self.userArray.append(card!.attending!)
self.latArray.append(card!.latitude!)
self.longArray.append(card!.longitude!)
self.timeArray.append(card!.time!)
self.locTextArray.append(card!.locationText!)
dispatch_async(dispatch_get_main_queue()) {
self.tableView.reloadData()
}
}
} catch {
print("There was an error")
}
}
myDataTask.resume()
print(nameArray)
}
