--- Comment #8 from Darin Adler <darin at apple.com> ---
Not sure if this comment is relevant to this bug, but I think there are two separate issues here:

1) What happens if a file's content is changed before the user triggers the user interface that starts the file uploading process. Certainly on legacy computer user interfaces like the one on a Mac it’s expected that the latest version of the file is uploaded, not a snapshot from back when the file was selected (chosen from a dialog, dragged, whatever). I’m guessing we’d expect the same thing from the file system on iOS, but a truly modern file system might get rid of the concept of "overwriting" a file.

2) What happens if a file's content is changed during the uploading process. In this case, I consider it a bug that you can upload a "damaged" file where content from two versions is mixed together, just because you made changes while the computer was sending data over the network.

I think it’s reasonable to consider fixing (2) even if it is practical to do it only on APFS. I think that kind of difference between file systems would be acceptable.
