ios - How to populate my tableView in Swift 2 from JSON? -

a new programmer here. how populate tableview json?
first problem json serialization , plugging in tableview.

code

import uikit  class legislatorstablevc: uitableviewcontroller {  // mark: variables & outlets private let cellidentifer = "cellreuse"  // mark: view did load override func viewdidload() {     super.viewdidload()      // creating congfiguration object // session created // getting info/data     let configuration = nsurlsessionconfiguration.defaultsessionconfiguration()     let session = nsurlsession(configuration: configuration)     let apikey = "https://congress.api.sunlightfoundation.com/legislators?apikey=xxxxxxxxxxxxxxxxxxxxx&all_legislators=true&per_page=all"      if let url = nsurl(string: apikey) {         // spawning task retrieve json data         session.datataskwithurl(url, completionhandler: { (data, response, error) -> void in             // checking error             if let error = error {                 print("the error is: \(error)")                 return             }             // response             if let httpresponse = response as? nshttpurlresponse httpresponse.statuscode == 200, let data = data {                 print("status code: \(httpresponse.statuscode)")                 // self.jsonserialization(data)             }         }).resume()     } } // end of view did load  // json serialization function swiftyjson.swift private func jsonserialization(data: nsdata){      // see gets status code 200 , i'm lost.     {         let json = try nsjsonserialization.jsonobjectwithdata(data, options: .mutablecontainers) as! [string: anyobject]      } catch {         print("error serializing json data: \(error)")     } } // end of jsonserialization    // mark: - table view data source // number of sections override func numberofsectionsintableview(tableview: uitableview) -> int {     // #warning incomplete implementation, return number of sections     return 1 } // end of number of sections  // number of rows in section override func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int {     // #warning incomplete implementation, return number of rows     return 15 } // end of number of rows in section  // cell row @ index path override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {     let cell = tableview.dequeuereusablecellwithidentifier(cellidentifer, forindexpath: indexpath) as! legislatortvcell      // configure cell...     cell.name.text = "name"     cell.title.text = "title"     cell.party.text = "party"      return cell } // end of cell row @ index path } 

• create custom class person outside view controller

  class person {   var firstname = ""   var lastname = ""   var title = ""   var party = "" } 

• create array of person in view controller

  var people = [person]() 

• the json has key results contains array of dictionaries.
  in viewdidload parse json , create person instances. reload table view.

  override func viewdidload() {   super.viewdidload()    // creating congfiguration object // session created // getting info/data   let configuration = nsurlsessionconfiguration.defaultsessionconfiguration()   let session = nsurlsession(configuration: configuration)   let apikey = "https://congress.api.sunlightfoundation.com/legislators?apikey=xxxxxxxxxxxxxxxxxx&all_legislators=true&per_page=all"    if let url = nsurl(string: apikey) {     // spawning task retrieve json data     session.datataskwithurl(url, completionhandler: { (data, response, error) -> void in       // checking error       if error != nil {         print("the error is: \(error!)")         return       } else if let jsondata = data {         {           let parsedjson = try nsjsonserialization.jsonobjectwithdata(jsondata, options: []) as! [string:anyobject]           guard let results = parsedjson["results"] as? [[string:anyobject]] else { return }           result in results {             let person = person()             person.firstname = result["first_name"] as! string             person.lastname = result["last_name"] as! string             person.party = result["party"] as! string             person.title = result["title"] as! string             self.people.append(person)           }           dispatch_async(dispatch_get_main_queue()) {             self.tableview.reloaddata()           }          } catch let error nserror {           print(error)         }       }     }).resume()   } } // end of view did load 

• the table view delegate methods clear when using custom class.
  since cellforrowatindexpath called code quite effective.

  override func numberofsectionsintableview(tableview: uitableview) -> int {   return 1 }  override func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int {   return people.count }  override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {   let cell = tableview.dequeuereusablecellwithidentifier(cellidentifer, forindexpath: indexpath) as! legislatortvcell    let person = people[indexpath.row]   cell.name.text = person.firstname + " " + person.lastname   cell.title.text = person.title   cell.party.text = person.party    return cell } // end 

of course couldn't test code might starting point.
