I just discovered this issue and found this thread. In our case, we have 30+ frameworks that we compile and link into our app. We started getting this missing dSym error for all of them, on top of the third party SDKs which do seem to be missing dSyms. In our case, the issue is mergable libraries. If we build with them on: MERGEABLE_LIBRARY = YES then we get warnings on every framework of ours. If we build with them off: MERGEABLE_LIBRARY = NO then the warnings for our frameworks go away.
