While NSFileManager.defaultManager()
is thread-safe, the file manager created by NSFileManager()
is not. So there is a possibility of creating the file manager in a thread, but using it in another. An ioQueue
could ensure all file IOs are in the same thread.
See the "Threading Considerations" section in NSFileManager doc.

Do you mean that self.fileManager
may be used when initializing an instance of ImageCache
?

Hi, in fact here should be no problem to just use fileManager = NSFileManager()
, or even use a defaultManager
. But if you want to add some delegate later, you will need a new created file manager and consider the thread problem.
Here I prefer a new file manager since Kingfisher is a framework and should be isolated in the io operations from the "host" app, which might be using the shared file manager.
