I need to copy file that downloaded from server and saved in doc listing to OTG usb machine linked to my iPhone, I can get path of usb machine however once I need to copy, transfer or write file to usb I get errors The file “STORAGE” couldn’t be saved within the folder “com.apple.filesystems.userfsd” and Permission denied (“Storage” is identify of the usb machine).
I used UIDocumentPickerViewController to get path of the usb.
I’ve tried to jot down information:
func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
guard let selectedURL = urls.first else { return }
do {
let shouldStopAccessing = selectedURL.startAccessingSecurityScopedResource()
defer {
if shouldStopAccessing {
selectedURL.stopAccessingSecurityScopedResource()
}
}
let information = attempt Information(contentsOf: fileURL!).base64EncodedData()
attempt information.write(to: selectedURL, choices: .noFileProtection)
print("Information written efficiently!")
do {
attempt FileManager.default.removeItem(atPath: fileURL!.path)
} catch {
print("Couldn't delete file, most likely read-only filesystem")
}
} catch {
print("Error writing information: (error.localizedDescription)")
}
}
even copy file with FileManager:
func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
guard let selectedURL = urls.first else { return }
do {
let shouldStopAccessing = selectedURL.startAccessingSecurityScopedResource()
defer {
if shouldStopAccessing {
selectedURL.stopAccessingSecurityScopedResource()
}
}
attempt FileManager.default.copyItem(at: fileURL!, to: selectedURL)
print("Information written efficiently!")
do {
attempt FileManager.default.removeItem(atPath: fileURL!.path)
} catch {
print("Couldn't delete file, most likely read-only filesystem")
}
} catch {
print("Error writing information: (error.localizedDescription)")
}
}
However none of those strategies labored.
Is there any approach to copy the file to the USB from iOS software?
