ios - Unable to display data in the second view controller using segue [Swift] -

i need pass data 1 view controller view controller. used segue (detail) , define model class named "photo".

tableviewcontroller looks following:

var photos = [photo]()  //strongly typed swift array      override func viewdidload() {         super.viewdidload()          var newphoto = photo(name:"cat ", filename:"cat", notes:"cat_file")         photos.append(newphoto)          var newphoto2 = photo(name:"r2 ", filename:"r2", notes:"r2")         photos.append(newphoto2)       } 

and other view controller (detailviewcontroller) looks following:

import uikit  class photodiplayviewcontroller: uiviewcontroller {      var currentphoto: photo?       @iboutlet weak var currentimage: uiimageview!       @iboutlet weak var currentlabel: uilabel!       override func viewdidload() {         super.viewdidload()          var image = uiimage(named: currentphoto!.filename)         self.currentimage.image = image          self.currentlabel.text = currentphoto?.name         println(currentphoto!.name  + currentphoto!.filename + currentphoto!.notes)      }      override func didreceivememorywarning() {         super.didreceivememorywarning()         // dispose of resources can recreated.     }   } 

when running program, table view loading fine , if click on cell going detail view controller. noting there in detail view controller. , used println() check , output coming in debugger following:

cat cat cat_file 

to pass data, used following segue code block:

override func prepareforsegue(segue: uistoryboardsegue, sender: anyobject?) {         // new view controller using [segue destinationviewcontroller].         // pass selected object new view controller.         var secondscene = segue.destinationviewcontroller as! photodiplayviewcontroller          if let indexpath = self.tableview.indexpathforselectedrow(){             let selectedphoto  = photos[indexpath.row]             secondscene.currentphoto = selectedphoto         }      } 

but still no luck! tried figure out missing? can tell me lagging?

update: complete detail view controller class code

update: full detail of table view code

import uikit  class phototableviewcontroller: uitableviewcontroller {      var photos = [photo]()  //strongly typed swift array      override func viewdidload() {         super.viewdidload()          var newphoto = photo(name:"cat ", filename:"cat", notes:"cat_file")         photos.append(newphoto)          var newphoto2 = photo(name:"r2 ", filename:"face.jpg", notes:"r2")         photos.append(newphoto2)       }      override func didreceivememorywarning() {         super.didreceivememorywarning()         // dispose of resources can recreated.     }      // mark: - table view data source      override func numberofsectionsintableview(tableview: uitableview) -> int {         // #warning potentially incomplete method implementation.         // return number of sections.         return 1     }      override func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int {         // #warning incomplete method implementation.         // return number of rows in section.         return photos.count     }       override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {         let cell = tableview.dequeuereusablecellwithidentifier("photocell", forindexpath: indexpath) as! uitableviewcell          var currentphoto = photos[indexpath.row]         cell.textlabel?.text = currentphoto.name          return cell     }       /*     // override support conditional editing of table view.     override func tableview(tableview: uitableview, caneditrowatindexpath indexpath: nsindexpath) -> bool {         // return no if not want specified item editable.         return true     }     */      /*     // override support editing table view.     override func tableview(tableview: uitableview, commiteditingstyle editingstyle: uitableviewcelleditingstyle, forrowatindexpath indexpath: nsindexpath) {         if editingstyle == .delete {             // delete row data source             tableview.deleterowsatindexpaths([indexpath], withrowanimation: .fade)         } else if editingstyle == .insert {             // create new instance of appropriate class, insert array, , add new row table view         }         }     */      /*     // override support rearranging table view.     override func tableview(tableview: uitableview, moverowatindexpath fromindexpath: nsindexpath, toindexpath: nsindexpath) {      }     */      /*     // override support conditional rearranging of table view.     override func tableview(tableview: uitableview, canmoverowatindexpath indexpath: nsindexpath) -> bool {         // return no if not want item re-orderable.         return true     }     */       // mark: - navigation      // in storyboard-based application, want little preparation before navigation     override func prepareforsegue(segue: uistoryboardsegue, sender: anyobject?) {         // new view controller using [segue destinationviewcontroller].         // pass selected object new view controller.         var secondscene = segue.destinationviewcontroller as! photodiplayviewcontroller          if let indexpath = self.tableview.indexpathforselectedrow(){             let selectedphoto  = photos[indexpath.row]             secondscene.currentphoto = selectedphoto         }      }   } 

don't use segue. use this, easier.

follow these steps...

1: create separate file called manager.swift , place code in it...

//manager.swift      import foundation      struct manager {      static var datatopass = string()       } 

2: clean project pressing shift+command+k.

3: in first view controller set datatopass data want pass...

manager.datatopass = self.datatopass 

4: in second view controller retrieve data , set content datatopass...

self.datatoreceive = manager.datatopass 

5: finished!!
