How to convert NSURL to String - ios

Question

I have a CameraVC class start with :
class CameraVC: UITableViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
var imagePicker = UIImagePickerController()
var image = UIImage()
var videoFilePath = NSURL()
...
I have this 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)
// THIS LINE IS 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 and i have a red alert with "Cannot convert value of type NSURL to expected argument type String.
The line :
print(self.videoFilePath)
write in console log :

Answer 1

Try looking at the documentation here: https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSURL_Class/#//apple_ref/occ/instp/NSURL/absoluteString
Try let url = NSURL(string: self.videoFilePath.absoluteString)
Also you do realise that self.videoFilePath is already an NSURL...

Answer 2

You have a poorly named variable. self.videoFilePath isn't a path, it's a url. You're making it a URL here:
self.videoFilePath = info[UIImagePickerControllerMediaURL] as! NSURL

Answer 3

If you already have self.videoFilePath as NSURL, you don't have to convert it to String and then NSURL
To keep the code safer:
if let path = info[UIImagePickerControllerMediaURL] as? NSURL {
self.videoFilePath = path
let url = path
//Continue whatever you want
}
