Swift 3 Garbage at End - php

Question

I am trying to receive info from my server but I keep getting the error telling me that there is Garbage at the end. It could be that the file being passed from the server has HTTP info as well but I do not know how to get rid of it. Here is my code:
class ViewController: UIViewController {
//URL to our web service
let URL_SAVE_TEAM = "http://<IP Address>/WebServerTest/api/createteam.php"
//TextFields declarations
#IBOutlet weak var textFieldName: UITextField!
#IBOutlet weak var textFieldMember: UITextField!
//Button action method
#IBAction func buttonSave(sender: UIButton) {
//created NSURL
let requestURL = NSURL(string: URL_SAVE_TEAM)
//creating NSMutableURLRequest
let request = NSMutableURLRequest(url: requestURL! as URL)
//setting the method to post
request.httpMethod = "POST"
//getting values from text fields
let teamName=textFieldName.text
let memberCount = textFieldMember.text
//creating the post parameter by concatenating the keys and values from text field
let postParameters = "name="+teamName!+"&member="+memberCount!;
//adding the parameters to request body
request.httpBody = postParameters.data(using: String.Encoding.utf8);
//creating a task to send the post request
let task = URLSession.shared.dataTask(with: request as URLRequest){
data, response, error in
if error != nil{
print("error is \(error)")
return;
}
//parsing the response
do {
//converting resonse to NSDictionary
let myJSON = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.allowFragments) as? NSDictionary
//parsing the json
if let parseJSON = myJSON {
//creating a string
var msg : String!
//getting the json response
msg = parseJSON["message"] as! String?
//printing the response
print(msg)
}
} catch {
print(error)
}
}
//executing the task
task.resume()
}
I am unable to see the issue.
