Swift: save video from NSURL to user camera roll

Question

I have a variable videoURL of type NSURL.

If I call println(videoURL) it would return something like this: http://files.parsetfss.com/d540f71f-video.mp4

I have a button set up that should take this videoURL and save the video to the user's camera roll.

The best I have done is this:

UISaveVideoAtPathToSavedPhotosAlbum(videoPath: String!, completionTarget: AnyObject!, completionSelector: Selector, contextInfo: UnsafeMutablePointer<Void>) 

While I'm not even sure if this will work or not, I can't figure out how to convert videoFile:NSURL into a videoPath.

Any help is appreciated on this.

Edit:

The following is unsuccessful:

UISaveVideoAtPathToSavedPhotosAlbum(videoURL.relativePath, self, nil, nil) 

Answer 1

AssetsLibrary is deprecated

1: import Photos

import Photos 

2: Use this code to save video from url to camera library.

PHPhotoLibrary.sharedPhotoLibrary().performChanges({              PHAssetChangeRequest.creationRequestForAssetFromVideoAtFileURL(nsUrlToYourVideo)          }) { saved, error in              if saved {                  let alertController = UIAlertController(title: "Your video was successfully saved", message: nil, preferredStyle: .Alert)                   let defaultAction = UIAlertAction(title: "OK", style: .Default, handler: nil)                  alertController.addAction(defaultAction)                  self.presentViewController(alertController, animated: true, completion: nil)              }          } 

Swift 3 & Swift 4

PHPhotoLibrary.shared().performChanges({     PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: urlToYourVideo) }) { saved, error in     if saved {         let alertController = UIAlertController(title: "Your video was successfully saved", message: nil, preferredStyle: .alert)         let defaultAction = UIAlertAction(title: "OK", style: .default, handler: nil)         alertController.addAction(defaultAction)         self.present(alertController, animated: true, completion: nil)     } } 

Answer 2

The accepted answer no longer works with Swift 3.0 & iOS 10.

First, you need to set the following permission in your app's plist file:

Privacy - Photo Library Usage Description

Provide a string that is presented to the user explaining why you are requesting the permission.

Next, import photos:

import Photos 

Finally, here is the updated code for Swift 3.0:

PHPhotoLibrary.shared().performChanges({     PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: fileURL) }) { saved, error in     if saved {         let alertController = UIAlertController(title: "Your video was successfully saved", message: nil, preferredStyle: .alert)         let defaultAction = UIAlertAction(title: "OK", style: .default, handler: nil)         alertController.addAction(defaultAction)         self.present(alertController, animated: true, completion: nil)     } }
