ios - Why is this data not displaying in my Swift 3 table -

so i'm trying parse json data retrieved server , display nicely in table, ive followed suggestions here: uitableview example swift , managed example working.

however data im parsing table remains blank. can see im going wrong?

import uikit import swiftyjson  class logsviewcontroller: uiviewcontroller, uitableviewdelegate, uitableviewdatasource {   let animals: [string] = ["horse", "cow", "camel", "sheep", "goat"]      var arraycount:int = 0          struct item {             let name : string             let locktime : string             let type : string         }     // cell reuse id (cells scroll out of view can reused)     let cellreuseidentifier = "cell"      var items = [item]()      @iboutlet weak var textuodate: uistackview!      override func viewdidload() {         super.viewdidload()         // register table view cell class , reuse id         self.tableview.register(uitableviewcell.self, forcellreuseidentifier: cellreuseidentifier)          tableview.delegate = self         tableview.datasource = self          // additional setup after loading view.         let lockid = userdefaults.standard.value(forkey: "lockid")!         //   let email = userdefaults.standard.value(forkey: "email")!           //get data server specific lock id          let u = userdefaults.standard.value(forkey: "userip")!         var request = urlrequest(url: url(string: "http://\(u):3000/logs")!)         request.httpmethod = "post"         let poststring = "lockid=\(lockid)"         request.httpbody = poststring.data(using: .utf8)         let task = urlsession.shared.datatask(with: request) { data, response, error in             guard let data = data, error == nil else {                                                              print("error=\(error)")                 return             }             if let httpstatus = response as? httpurlresponse, httpstatus.statuscode != 200 {           // check http errors                 print("statuscode should 200, \(httpstatus.statuscode)")                 print("response = \(response)")                 print(response ??

data not displaying because didn't reload table view after append items array. please reload table view @ end of task closure

let task = urlsession.shared.datatask(with: request) { data, response, error in      // ......     // ......     self.tableview.reloaddata() }
