could not reparse object file in bitcode bundle: 'Invalid bitcode version

Question

ld: could not reparse object file in bitcode bundle: 'Invalid bitcode version (Producer: '902.0.39.2_0' Reader: '900.0.39.2_0')', using libLTO version 'LLVM version 9.0.0, (clang-900.0.39.2)' for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Note: - Enable Bitcode to No in Build Settings. Apple Reject on uploading build to itune.

I've never seen this error before, but it looks to me like you are linking against a library that was pre-build with a newer, and unfortunately incompatible, compiler version.

The only options I can think of are to update your compiler or rebuild the library.

I would imagine this library isn't building by you, or you'd have tried that already. So, your only option seems to be updating your version of Xcode to be at least the same as was used for this library.
