ios - How to convert NSURL to String -


i have cameravc class start :

class cameravc: uitableviewcontroller, uiimagepickercontrollerdelegate, uinavigationcontrollerdelegate {  var imagepicker = uiimagepickercontroller() var image = uiimage() var videofilepath = nsurl()  ...

i have function :

func imagepickercontroller(picker: uiimagepickercontroller, didfinishpickingmediawithinfo info: [string : anyobject]) {      let mediatype:string = info[uiimagepickercontrollermediatype] as! string      print(mediatype)      if mediatype == "public.image" {         self.image = info[uiimagepickercontrolleroriginalimage] as! uiimage          if self.imagepicker.sourcetype == uiimagepickercontrollersourcetype.camera {             uiimagewritetosavedphotosalbum(self.image, nil, nil, nil)         }          self.dismissviewcontrolleranimated(true, completion: nil)      } else if mediatype == "public.movie" {         self.videofilepath = info[uiimagepickercontrollermediaurl] as! nsurl         print(self.videofilepath)          // line not work ->         let url = nsurl(string: self.videofilepath)          /*if self.imagepicker.sourcetype == uiimagepickercontrollersourcetype.camera {             if uivideoatpathiscompatiblewithsavedphotosalbum(self.videofilepath) {                 uisavevideoatpathtosavedphotosalbum(self.videofilepath, nil, nil, nil)             }         }*/     }  }

the line : 

    let url = nsurl(string: self.videofilepath)

is not working , have red alert "cannot convert value of type nsurl expected argument type string.

the line :

print(self.videofilepath)

write in console log :

file:///private/var/mobile/containers/data/application/071bca9c-d246-4d14-9d56-34057a17079b/tmp/capture-t0x156501280.tmp.y4ve7u/capturedvideo.mov

if have self.videofilepath nsurl, don't have convert string , nsurl

to keep code safer:

if let path = info[uiimagepickercontrollermediaurl] as? nsurl {     self.videofilepath = path     let url = path     //continue whatever want }

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -
