Getting URL for PHAsset (Swift 3.0)

thanks for sharing the snippet.
I would just add - in order to fetch videos stored in iCloud (otherwise result handler will return nil) - set PHVideoRequestOptions's param isNetworkAccessAllowed to be true.

@freemansion greatly appreciate for pointing that important case out.

Thanks! I slightly changed it for what i need

    func requestAssetUrl() -> AnyPublisher<URL, Error> {
        Future { [self] promise in
            if self.mediaType == .image {
                self.requestContentEditingInput(with: nil) { input, info in
                    if let input = input, let url = input.fullSizeImageURL {
                        promise(.success(url))
                    } else {
                        promise(.failure(Errors.urlNotAvailable))
                    }
                }
            } else if self.mediaType == .video {
                let options: PHVideoRequestOptions = PHVideoRequestOptions()
                options.version = .original
                PHImageManager.default().requestAVAsset(forVideo: self, options: options) { asset, audio, info in
                    if let urlAsset = asset as? AVURLAsset {
                        let localVideoUrl = urlAsset.url
                        promise(.success(localVideoUrl))
                    } else {
                        promise(.failure(Errors.urlNotAvailable))
                    }
                }
            } else {
                promise(.failure(Errors.mediaNotSupported))
            }
        }.eraseToAnyPublisher()
    }
    
    extension PHAsset {
      enum Errors: Error {
          case urlNotAvailable
          case mediaNotSupported
      }
    }

@fernandodev I recommend you add some code that shows how to use this piece. Newbies would need it, but that definitely helped. Thanks!
