ios - Swift 2: Update UIImage Dictionary with UIImage() var from UIImagePicker -

-

i have 2 viewcontrollers. viewcontroller#1 contains uiimagepicker , viewcontroller #2 contains uiimage dictionary variable key. update dictionary array uiimage variable (var newimage = uiimage() )that passed viewcontroller#1.the array expecting string tried converting uiimage array string. confirmed image no luck.any ideas?

viewcontroller#1:    class viewcontroller: uiviewcontroller,uinavigationcontrollerdelegate,uiimagepickercontrollerdelegate {      let imagepicker = uiimagepickercontroller()     var images = [uiimage]()     var testimage = uiimage()      @iboutlet weak var beaconone: uitextfield!     @iboutlet weak var beacontwo: uitextfield!     @iboutlet weak var backimage: uiimageview!     @iboutlet weak var majorid2: uitextfield!      @ibaction func pickphoto(sender: uibarbuttonitem) {          imagepicker.allowsediting = true         imagepicker.modalpresentationstyle = .popover         imagepicker.sourcetype = .photolibrary         imagepicker.delegate = self          self.presentviewcontroller(imagepicker, animated: true, completion: nil)      }      func imagepickercontroller(picker: uiimagepickercontroller, didfinishpickingimage pickedimage: uiimage, editinginfo: [string : anyobject]?) {          testimage = pickedimage         self.dismissviewcontrolleranimated(true, completion: nil)         print(images)       }        override func viewdidload() {         super.viewdidload()            }       override func prepareforsegue(segue: uistoryboardsegue, sender: anyobject?) {         let planvc = segue.destinationviewcontroller as! planagramviewcontroller          planvc.newimage = testimage       }   }     viewcontroller#2:  // //  viewcontroller.swift //  beacontest // //  created apple on 5/6/16. //  copyright © 2016 apple. rights reserved. // // uses corelocation framework    import uikit import corelocation   class planagramviewcontroller: uiviewcontroller,cllocationmanagerdelegate,uiimagepickercontrollerdelegate,uinavigationcontrollerdelegate {      @iboutlet weak var imageview: uiimageview!      @iboutlet weak var testimageview: uiimageview!       var newimage = uiimage()     var beaconimages = [51098: uiimage(named: "plan_p"),21714: uiimage(named: "plan_m")]       override func viewdidload() {         super.viewdidload()          let newvcmajorid = int(vcmajorid1)         beaconimages.updatevalue(uiimage(named: "plan_p"), forkey: newvcmajorid!)          let newvcmajorid2 = int(vcmajorid2)         beaconimages.updatevalue(uiimage(named: "plan_m"), forkey: newvcmajorid2!)         }   }

here's should . grab (in code)the planogram view controller ui story board , send image new image , in view controller # 2 use value.

view controller #2

import uikit import corelocation   class planagramviewcontroller: uiviewcontroller,cllocationmanagerdelegate,uiimagepickercontrollerdelegate,uinavigationcontrollerdelegate {       @iboutlet weak var imageview: uiimageview!      @iboutlet weak var testimageview: uiimageview!     var newimage : uiimage?     var beaconimages = [51098: uiimage(named: "image"),21714: uiimage(named: "image")]       override func viewdidload() {         super.viewdidload()          beaconimages.updatevalue(newimage, forkey: 51098)           beaconimages.updatevalue(newimage, forkey: 21714)          imageview.image = beaconimages[21714]!         testimageview.image = beaconimages[51098]!         }   }

view controller #1 change below function , remove prepare segue method . 

 func imagepickercontroller(picker: uiimagepickercontroller, didfinishpickingimage pickedimage: uiimage, editinginfo: [string : anyobject]?) {          testimage = pickedimage          self.dismissviewcontrolleranimated(true, completion: nil)         images.append(testimage)            let        planvc = uistoryboard.init(name: "main", bundle: nil).instantiateviewcontrollerwithidentifier("planagram") as? planagramviewcontroller      planvc?.newimage = testimage         self.presentviewcontroller((planvc)!             , animated: true, completion: nil)      }
