Sorry to resurrect an almost year-old-thread, but this issue is quite relevant for my company too.
Having RadaeePDF SDK not Bitcode-enabled is forcing all users to disable this option on their applications too.
Bitcode is mandatory for most code hardening tools nowadays, so it would be very important to enable it in RadaeePDF SDK.
It is clear that Apple is "gently forcing" all developers to distribute libraries and apps with Bitcode enabled, so it is reasonable to think that the problem you mentioned with assembly code is already addressed and solved.
In fact I've found this comment by Apple that explains how to build a Bitcode enabled library containing assembly code (
Please consider releasing a Bitcode enabled version of your SDK.
Thanks a lot
