Distill failed for unknown reasons (xcode 11 beta 5
I got the same problem but I have fixed it.
In my case, there was a wrong image file in an asset.
For example, the "background" asset has two appearances (Any and Dark). By the way, the dark appearance image source file has the error that the file size is zero.
This is the correct answer!
Catch this on 12.0.1 (12A7300). Trying to understand what the reasons....
Find the solution - check all files in Assets, find the corrupted one and removed it from Assets. All work fine now.
