I believe the command you give to check if bitcode is enabled is not entirely correct. I was recently debugging an issue where bitcode was not generated for a framework I was using, and my build failed complaining about the framework missing bitcode. While that framework did have `__LLVM` segments, there was no `__bitcode` subsegment.
There’s some discussion around that on this SO question: https://stackoverflow.com/questions/32808642/how-to-check-if... (but also no definitive answer)
