Distill failed for unknown reasons (xcode 11 beta 5

Seems it's not fixed yet in XCode beta 7.

I had this too, with Xcdoe11beta7 (Version 11.0 beta 6 (11M392r))

Don't cry; file a bug report. I'm encounter it, as well 😟

Version 11.0 (11A419c) still has this problem

Still an issue on 11 GM 😟 Any solutions?

Any solution so far? Xcode 11 GM

I resolve it by upgrading my os version(10.15 beta2 ->10.15 beta8).

Can confirm, this fixes it.

Issue still on Xcode 11 production 😢

Same.

Update system to macOS Catalina 10.15 Beta 9. fix this bug.

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!
