Xcode error : Distill failed for unknown reasons
Does anybody know why this error happens on Xcode 5?
Answer
I had this problem when I accidentally renamed a .psd as a .png. Converting the image to an actual png instead of a Photoshop file fixed it for me.
I found that my png was a psd file. I deleted the file and recreated a new png and everything was fine.

I had the same case as Karsten, one of the image was psd. I opened the file in Mac Preview app and tried to export and found that it was a PSD instead of .png
