ios - Swift 2.0 Core Data - TableView not reading NSManagedObject -

in first view controller saved data in core data uitextfields, wanted tableview read data in second view controller, got no errors got no display of data in tableview cells. in first vc made property of nsmanaged object, , in second vc retrieve object, put in tableview no data displayed. crucial understanding how tableview can read data core data, thank lot.

first vc

import uikit import coredata  class viewcontroller: uiviewcontroller {  @iboutlet weak var namefield: uitextfield!  @iboutlet weak var passfield: uitextfield!  var item = [nsmanagedobject]()  override func viewdidload() {     super.viewdidload()  }  override func didreceivememorywarning() {     super.didreceivememorywarning()  }  @ibaction func saveinfo(sender: uibutton) {      let appdel: appdelegate = uiapplication.sharedapplication().delegate as! appdelegate     let context: nsmanagedobjectcontext = appdel.managedobjectcontext      //add new user     let newuser = nsentitydescription.insertnewobjectforentityforname("users", inmanagedobjectcontext: context)     newuser.setvalue(namefield.text, forkey: "username")     newuser.setvalue(passfield.text, forkey: "passwords")      // add info entity     do{         try context.save()     }catch{         print("error, data not saved!")     }      // retrieve data      do{          let request = nsfetchrequest(entityname: "users")         let results = try context.executefetchrequest(request)          if results.count > 0 {              item in results as! [nsmanagedobject]{                  let name = item.valueforkey("username")                 let password = item.valueforkey("passwords")                  print(name!, password!)         }         }          }catch{          print("erorr, data not read!")     }      namefield.text = ""     passfield.text = ""      }// end of button function   } 

second vc aka tableview

import uikit import coredata  class tableviewcontroller: uiviewcontroller, uitableviewdelegate, uitableviewdatasource {  @iboutlet weak var tableview: uitableview!  var bridge: viewcontroller = viewcontroller()  var array = [nsmanagedobject]()  override func viewdidload() {     super.viewdidload()      self.array = self.bridge.item      self.tableview.delegate = self     self.tableview.datasource = self }  override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }  func tableview(tableview:uitableview, numberofrowsinsection section:int) -> int {     return array.count }  func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {      let cell = tableview.dequeuereusablecellwithidentifier("cell", forindexpath: indexpath)      let person = array[indexpath.row]     cell.textlabel!.text = person.valueforkey("username") as? string     return cell }  }
