Document file path unreachable in swift - swift

Question

I'm currently working on a small swift application and I'm storing some video records in the documents folder of the app. I would like to retrieve these on a later moment. I already got an array of file locations like this:
file:///private/var/mobile/Containers/Data/Application/6C462C4E-05E2-436F-B2E6-F6D9AAAC9361/Documents/videorecords/196F9A75-28C4-4B65-A06B-6111AEF85F01.mov
Now I want to use such file location to create a thumbnail with the first frame and connect that to my imageview with the following piece of code:
func createVideoStills() {
for video in directoryContents {
print("\(video)")
do {
let asset = AVURLAsset(URL: NSURL(fileURLWithPath: "\(video)"), options: nil)
let imgGenerator = AVAssetImageGenerator(asset: asset)
imgGenerator.appliesPreferredTrackTransform = true
let cgImage = try imgGenerator.copyCGImageAtTime(CMTimeMake(0, 1), actualTime: nil)
let uiImage = UIImage(CGImage: cgImage)
videoCell.imageView = UIImageView(image: uiImage)
//let imageView = UIImageView(image: uiImage)
} catch let error as NSError {
print("Error generating thumbnail: \(error)")
}
}
}
The first print gives me a path like described above. But the AVURLAsset doesn't like this path because it spits out the following error:
Error generating thumbnail: Error Domain=NSURLErrorDomain Code=-1100
"The requested URL was not found on this server."
UserInfo={NSLocalizedDescription=The requested URL was not found on
this server., NSUnderlyingError=0x14ee29170 {Error
Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}
Which is weird cause it is right there. Any solutions on how to fix/solve this?
Kind regards,

Answer 1

The output of your print("\(video)") is not a file path but a string representation of file URL. You need to use init(string:) than init(fileURLWithPath:) of NSURL.
See what you get with:
let asset = AVURLAsset(URL: NSURL(string: video), options: nil)
(Unnecessary string interpolation would generate some unexpected result without errors -- like getting "Optional(...)", so you should avoid.)

Answer 2

// if You Are Using PHPickerViewController then do this for fetching the url.
// ------
func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
picker.dismiss(animated: true, completion: nil)
guard let provider = results.first?.itemProvider else { return }
if provider.hasItemConformingToTypeIdentifier(UTType.movie.identifier) {
provider.loadItem(forTypeIdentifier: UTType.movie.identifier, options: [:]) { [self] (videoURL, error) in
print("resullt:", videoURL, error)
DispatchQueue.main.async {
if let url = videoURL as? URL {
let player = AVPlayer(url: url)
let playerVC = AVPlayerViewController()
playerVC.player = player
present(playerVC, animated: true, completion: nil)
}
}
}
}
}
