wait_fences: failed to receive reply: 10004003 (Again)

Question

Another cry for help about this warning.

First of all I have looked at every and all questions on here elsewhere and none seem to fit my situation. It has nothing to do

Answer 1

I've ran into the wait_fences error when mistakenly running UIKit code from a background thread. It doesn't sound like that's your problem, but if you haven't yet that's another thing to look into.
