Trying to send web request in swift (IOS) - ios

Question

I looked up how to send a request, and found the answer on here, but while it seems to work for everyone else, it won't for me. Can some please please help me get the code to actually send the POST request, and print the response. The URL works, because I can manually enter in the information via my borwser, but it is a LAN website, but this app is just for learning SWIFT.
import UIKit
class PostController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func sendPost(url:String,attrs:String) {
print("YO BOY")
var request = URLRequest(url: URL(string: url)!)
request.httpMethod = "POST"
let postString = attrs
request.httpBody = postString.data(using: .utf8)
print("NABBBADABBA")
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else { // check for fundamental networking error
print("error=\(String(describing: error))")
return
}
print("CHIKKA CHIKKA")
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(String(describing: response))")
}
print("FLEKKA FLEEKA WAHAPPA")
let responseString = String(data: data, encoding: .utf8)
print("responseString = \(String(describing: responseString))")
}
task.resume()
}
#IBOutlet var text: UITextView!
#IBAction func post(_ sender: Any) {
print("SENDING POST")
sendPost(url: "localhost/testingtest.php",attrs: "post=\(text.text)")
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
*/
}
`
my problem is happening somewhere here
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else { // check for fundamental networking error
print("error=\(String(describing: error))")
return
}
with the terminal saying:
SENDING POST
YO BOY
NABBBADABBA
