Hello,
I had a strange bug in a File Provider app and I found out that the problem was that NSFileProviderEnumerator's invalidate() was called during an operation (a download or even a file enumeration operation from the server).
The files are stored on a server and while fetchContent is called and the extension waits for the server to send the file (or enumerate a long list of files), invalidate() is called. And after some time the extension is re-initialised.
I know that the extension can be deallocated by the OS from time to time, but why during an operation? If a do a cleanup inside invalidate() I will lose references to my downloads or operations.
Any thoughts on this? Is there any way to prevent this?
Thank you.
