ios - No such file location - Uploading image from Swift to S3 -

i trying upload image amazon s3 getting following error:

optional(error domain=nscocoaerrordomain code=260 "the file “asset.jpg” couldn’t opened because there no such file." userinfo={nsfilepath=/asset.jpg, nsunderlyingerror=0x7fb0d8eb3b00 {error domain=nsposixerrordomain code=2 "no such file or directory"}})

the below code getting image or videos file path - stored in variable 'filelocation':

func imagepickercontroller(picker: uiimagepickercontroller, didfinishpickingmediawithinfo info: [string : anyobject]) {     //let mediatype2 : uiimage = info[uiimagepickercontrolleroriginalimage] as! uiimage     let mediatype : cfstring = info[uiimagepickercontrollermediatype] as! cfstring        //if video - save     if mediatype == kuttypemovie {         let path = (info[uiimagepickercontrollermediaurl] as! nsurl).path         if uivideoatpathiscompatiblewithsavedphotosalbum(path!) && savevideovar == true{             uisavevideoatpathtosavedphotosalbum(path!, self, "video:didfinishsavingwitherror:contextinfo:", nil)         }     }     else{         let img : uiimage = info[uiimagepickercontrolleroriginalimage] as! uiimage         let screensize: cgrect = uiscreen.mainscreen().bounds          var multiplynum = screensize.width / img.size.width         //if image height going more 60% of screen, resize width , height ensure isn't greater 60% while keeping aspect ratio correct         if ((img.size.height*multiplynum) > (screensize.height*0.6)){             multiplynum = screensize.height*0.6 / img.size.height             imageviewwidthconstraint.constant = (multiplynum*img.size.width)             imageviewheightconstraint.constant = screensize.height*0.6         }         else{             imageviewwidthconstraint.constant = screensize.width             imageviewheightconstraint.constant = (multiplynum*img.size.height)         }         imageview.image = img      }     let filelocation: nsurl = info["uiimagepickercontrollerreferenceurl"] as! nsurl     nwyt.uploads3(filelocation)      self.dismissviewcontrolleranimated(true, completion: {})  } 

no matter photo chose, gives same error file "asset.jpg" couldn't opened..." though when print filelocation, path more complex that, example: "assets-library://asset/asset.jpg?id=ec41ac54-cebd-49aa-a1fa-864370d103c0&ext=jpg"

implementation of nwyt.uploads3() :

func uploads3(filebody : nsurl){     let uploadrequest: awss3transfermanageruploadrequest = awss3transfermanageruploadrequest()     uploadrequest.bucket = "bx-video"     uploadrequest.key = "testobject.jpg"     uploadrequest.body = filebody     print(filebody)      let transfermanager: awss3transfermanager = awss3transfermanager.defaults3transfermanager()     transfermanager.upload(uploadrequest).continuewithexecutor(awsexecutor.mainthreadexecutor(), withblock: {(task: awstask) -> anyobject! in         if task.error != nil {             print(task.error)             nslog("error uploading : " + uploadrequest.key!)         }         else {             nslog("upload completed : " + uploadrequest.key!)         }         return nil     }) } 

solution below:

if let img : uiimage = imageview.image! uiimage{                 let path = (nstemporarydirectory() nsstring).stringbyappendingpathcomponent("image.png")                 let imagedata: nsdata = uiimagepngrepresentation(img)!                 imagedata.writetofile(path string, atomically: true)                  // once image saved can use path create local fileurl                 let url:nsurl = nsurl(fileurlwithpath: path string)                 nwyt.uploads3(url)              }
