FileManager returns permission error while trying to get the file size, in iOS 13 devices.

do {
    let attr = try FileManager.default.attributesOfItem(atPath: my_file_path) //--> Getting nil
    fileSize = attr[FileAttributeKey.size] as! UInt64
} catch {
    print("Error: \(error)")
}

Error returned:

Error Domain=NSCocoaErrorDomain Code=257 "The file “trim.1A9FFC19-EE2C-438A-BF3D-97E05A97EF9E.MOV” couldn’t be opened because you don’t have permission to view it." UserInfo={NSFilePath=/private/var/mobile/Containers/Data/PluginKitPlugin/ADB8684E-12B5-451D-A20F-158B899BB3DD/tmp/trim.1A9FFC19-EE2C-438A-BF3D-97E05A97EF9E.MOV, NSUnderlyingError=0x280af0510 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}}

The issue observed only after I updated to iOS 13. In earlier versions everything is working fine.

iOS 13 SDK consider photo app as an another app, so when we dismiss the image picker controller video url will be invalidate.

I had the problem before when I try to upload video to AWS, what i did just create a temporary folder and copy the existing video url path before dismiss the Image-picker.then it upload, it's worked.

    func createDirectory(videoURL:URL){
            let Directorypath = getDirectoryPath()
            var objcBool:ObjCBool = true
            let isExist =  FileManager.default.fileExists(atPath:Directorypath,isDirectory: &objcBool)
            // If the folder with the given path doesn't exist already, create it
            if isExist == false{
                do{
                    try FileManager.default.createDirectory(atPath: Directorypath, withIntermediateDirectories: true, attributes: nil)
                }catch{

                    print("Something went wrong while creating a new folder")
                }
            }
            let fileManager = FileManager()

            do {
                if fileManager.fileExists(atPath:Directorypath) {
                    try? fileManager.removeItem(at: URL(fileURLWithPath:Directorypath))
                }
                try fileManager.copyItem(at:videoURL.absoluteURL, to: URL(fileURLWithPath:Directorypath))

                 self.imagePicker.dismiss(animated: true, completion:nil)
              }catch let error {
                              print(error.localizedDescription)
              }

   }
