UnityCloudBuild IOS invalid bitcode

Hi...
I got this error when build ios on unity cloud build

I use version 2019.3.10f1
FB SDK 8.1.0
XCode 11.4.1

no clue what the cause is. work fine before.

ld: could not reparse object file in bitcode bundle: 'Invalid bitcode version (Producer: '1200.0.32.2.0_0' Reader: '1103.0.32.59_0')', using libLTO version 'LLVM version 11.0.3, (clang-1103.0.32.59)' for architecture arm64

 

We are facing the same issue, it seems that the selected XCode version might be too old... we aren't the only ones with this issue.
