ios - SWIFT - Property not seen outside viewdidload -

i try pass string vc1 vc2, value of tex passed property detailitem loaded viewdidload, , not in function

viewcontroller 1:

@iboutlet var tex: uitextfield! // prepare fore segue pass value of txt   override func prepareforsegue(segue: uistoryboardsegue, sender: anyobject?) {   if segue.identifier? == "todo" {     let navvc = segue.destinationviewcontroller uinavigationcontroller     let itemvc: checklistviewcontroller = navvc.topviewcontroller checklistviewcontroller     itemvc.detailitem! = tex.text   }  } 

viewcontroller 2:

var detailitem : string!  // can see value of tex in viewdidload  override func viewdidload() {   super.viewdidload()    println("viewdidload \(detailitem)")   tableview.rowheight = 44 }  // here , in  function below result nil. required init(coder adecoder: nscoder) {   println("print init \(detailitem)")   items = [checklistitem]()   super.init(coder: adecoder)   loadchecklistitems() }  func documentsdirectory() -> string {   let paths = nssearchpathfordirectoriesindomains(.documentdirectory, .userdomainmask, true) [string]   return paths[0] }  func datafilepath() -> string {   println("print path\(detailitem)")   return documentsdirectory().stringbyappendingpathcomponent("checklists.plist") }  func savechecklistitems() {   let data = nsmutabledata()   let archiver = nskeyedarchiver(forwritingwithmutabledata: data)   archiver.encodeobject(items, forkey: "checklistitems")   archiver.finishencoding()   data.writetofile(datafilepath(), atomically: true)   println("print save\(detailitem)") }  func loadchecklistitems() {   let path = datafilepath()   if nsfilemanager.defaultmanager().fileexistsatpath(path) {     if let data = nsdata(contentsoffile: path) {       println("print load\(detailitem)")       let unarchiver = nskeyedunarchiver(forreadingwithdata: data)       items = unarchiver.decodeobjectforkey("checklistitems") [checklistitem]       unarchiver.finishdecoding()     }   } } 

console output:

print init  print path print load viewdidload antwerp 

thanks alberto

you can't see property in initializer because code called before itemvc.detailitem! = tex.text.

you move call loadchecklistitems() viewdidload(). load items detail item set:

var detailitem : string! {     didset {         loadchecklistitems()     } }
