NSURL Request is not working - ios

Question

I have a request, after it I need a full Dictionary. But when I checked my request with breakpoints, I saw that it jump over my request... What is wrong in it?
func downloadPackages() {
let url = "\(URL_BASE)package/list?id=666"
let dataURL = NSURL(string: url)
let dataRequest = NSURLRequest(URL: dataURL!)
let dataSession = NSURLSession.sharedSession()
print("QQ")
let dataTask = dataSession.dataTaskWithRequest(dataRequest) { (data, response, error) -> Void in
print("QQ2")
if error != nil {
print(error.debugDescription)
} else {
do {
let packageDict = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments) as? Dictionary<String, AnyObject>
if let results = packageDict!["data"] as? [Dictionary<String, AnyObject>] {
for obj in results {
let package = Package(packageDict: obj)
print(self.monsters.count)
self.monsters.append(package)
}
}
//Main UI thread
dispatch_async(dispatch_get_main_queue()) {
self.tableView.reloadData()
}
}
catch {
}
}
}
dataTask.resume()
}
It doesn't print ("QQ2"), but it prints ("QQ").

I think that you didn't add HTTP Request methods and values. So try like this :-
func downloadPackages() {
let url = "\(URL_BASE)package/list?id=666"
let dataURL = NSURL(string: url)
let dataRequest: NSMutableURLRequest = NSMutableURLRequest(URL: dataURL!)
dataRequest.HTTPMethod = "POST"
dataRequest.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
dataRequest.setValue("*/*", forHTTPHeaderField: "Accept")
let dataSession = NSURLSession.sharedSession()
print("QQ")
let dataTask = dataSession.dataTaskWithRequest(dataRequest) { (data, response, error) -> Void in
print("QQ2")
if error != nil {
print(error.debugDescription)
} else {
do {
let packageDict = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments) as? Dictionary<String, AnyObject>
if let results = packageDict!["data"] as? [Dictionary<String, AnyObject>] {
for obj in results {
let package = Package(packageDict: obj)
print(self.monsters.count)
self.monsters.append(package)
}
}
//Main UI thread
dispatch_async(dispatch_get_main_queue()) {
self.tableView.reloadData()
}
}
catch {
}
}
}
dataTask.resume()
}

i think you made a syntax mistake:-
dispatch_async(dispatch_get_main_queue(), {
self.tableView.reloadData()
})
and yes wait for a sec for uitableview to be populated.
Following would be better way:-
dispatch_async(dispatch_get_main_queue(), {
for obj in results {
let package = Package(packageDict: obj)
print(self.monsters.count)
self.monsters.append(package)
}
dispatch_async(dispatch_get_main_queue(), {
self.tableView.reloadData()
})
})
rest seems to be fine.
