Yeah it seems like sketchtool is a different kind of executable and class-dump is unable to read it. You might need to use a disassembler to peek at the headers instead of using class-dump.

I'm curious why you're looking for sketchtool headers though.

sorry, my mistake, I use "class-dump -H Sketch -o /output"
