                    var mystring =  self.answer.components(separatedBy:"=")
                       let size = mystring.count
                    var i = 0
                    while (i < size-1 )
                    {
                        let st1 = mystring[i+1]
                         self.list = st1.components(separatedBy: ";")
                        print (self.list[0])
                        i += 1

    }
    task.resume()


    // Do any additional setup after loading the view, typically from a nib.

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.

public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
    return(list.count)
}


    public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
    {
        let cell = UITableViewCell(style: UITableViewCellStyle.default, reuseIdentifier: "cell")
        cell.textLabel?.text = list[indexPath.row]
        return(cell)
    }
}

DispatchQueue.main.async - for update the UI why because network call is background queue .

 do {
     let myJson = try JSONSerialization.jsonObject(with: content, options: JSONSerialization.ReadingOptions.mutableContainers) as! NSDictionary
       let asd = myJson.value(forKey: "getlocationResult")
       self.answer = String(describing: asd!)
       var mystring =  self.answer.components(separatedBy:"=")
       let size = mystring.count
        var i = 0
       while (i < size-1 )
         {
            let st1 = mystring[i+1]
            self.list = st1.components(separatedBy: ";")
            print (self.list[0])
            i += 1
           }
         DispatchQueue.main.async(execute: { () -> Void in
            self.yourTableViewName.reloadData()  
          })
   }
   catch
   {
   }
