NSFileManager delete contents of directory

Question

How do you delete all the contents of a directory without deleting the directory itself? I want to basically empty a folder yet leave it (and the permissions) intact.

Answer 1

You can extend the NSFileManager like this:

extension NSFileManager {
  func clearFolderAtPath(path: String) -> Void {
      for file in subpathsOfDirectoryAtPath(path, error: nil) as? [String] ?? []  {
          self.removeItemAtPath(path.stringByAppendingPathComponent(file), error: nil)
      }
  }
}

Then, you can clear the folder like this: NSFileManager.defaultManager().clearFolderAtPath("the folder's path")
