iCloud Drive Splitting Folders

Drew McCormack:

It’s difficult to know exactly what is happening, but it seems iCloud Drive is generating extraneous folders during conflict resolution.

For many apps, this is no big deal, and may never arise. But if your app stores data at specific paths in iCloud Drive, it could very easily become a problem.

If you are removing and re-adding folders in your app at a specific path in iCloud Drive, don’t be surprised if one day you discover the data is gone, and moved into a second version of the folder at a different path.

I consider this pretty undesirable behavior. No other sync solution I know does this. Dropbox doesn’t — although Dropbox does do something similar to this with files rather than directories — and the original iCloud file sync also didn’t do it.
