Saving video in locally (directory) in Swift? - ios

Question

I try to save given video locally after then I need those saved videos for playing video in my app. I can't handle the saving video. Here is my saving try :
func saveVideoDocumentDirectory(url : URL){
let fileManager = FileManager.default
let paths = (NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString).appendingPathComponent(".MOV")
do{
let videoData = try Data(contentsOf: url)
fileManager.createFile(atPath: paths as String, contents: videoData, attributes: nil)
}catch{
//
}
}
here is the get file try
func getVideo(){
let fileManager = FileManager.default
let videoPAth = (self.getDirectoryPath() as NSString).appendingPathComponent(".MOV")
if fileManager.fileExists(atPath: videoPAth){
print(videoPAth)
play(url: URL(string: videoPAth)!)
}else{
print("No Video")
}
}
here is my play video func :
func play(url : URL)
{
let player = AVPlayer(url: url)
let playerViewController = AVPlayerViewController()
playerViewController.player = player
present(playerViewController, animated: true)
{
playerViewController.player!.play()
}
}

Instead of Filemanager.createFile(), try using write instead.
let videoData = try Data(contentsOf: url)
try videoData.write(to: paths, options: .atomic)
Also, I recommend creating a folder first (from this answer).
extension URL {
static func createFolder(folderName: String) -> URL? {
let fileManager = FileManager.default
// Get document directory for device, this should succeed
if let documentDirectory = fileManager.urls(for: .documentDirectory,
in: .userDomainMask).first {
// Construct a URL with desired folder name
let folderURL = documentDirectory.appendingPathComponent(folderName)
// If folder URL does not exist, create it
if !fileManager.fileExists(atPath: folderURL.path) {
do {
// Attempt to create folder
try fileManager.createDirectory(atPath: folderURL.path,
withIntermediateDirectories: true,
attributes: nil)
} catch {
// Creation failed. Print error & return nil
print(error.localizedDescription)
return nil
}
}
// Folder either exists, or was created. Return URL
return folderURL
}
// Will only be called if document directory not found
return nil
}
}
Then, you can save like this:
guard let folderURL = URL.createFolder(folderName: "StoredVideos") else {
print("Can't create url")
return
}
let permanentFileURL = folderURL.appendingPathComponent(nameOfYourFile).appendingPathExtension("MOV")
let videoData = try Data(contentsOf: url)
try videoData.write(to: permanentFileURL, options: .atomic)
This will save you the hassle of NSSearchPathForDirectoriesInDomains.
