UnityException: Failed assemblies stripper

 유니티3D iOS 프로젝트를 빌드 중 아래와 같이 2개의 오류가 발생했습니다.

UnityException: Failed assemblies stripper: /Applications/Unity/Unity.app/Contents/Frameworks/Mono/bin/mono "/Applications/Unity/Unity.app/Contents/Frameworks/Tools/UnusedByteCodeStripper/UnusedBytecodeStripper.exe" -l none -c link -a "Assembly-CSharp-firstpass.dll" -a "Assembly-CSharp.dll" -out output -x "/Applications/Unity/Unity.app/Contents/Frameworks/Tools/UnusedByteCodeStripper/link.xml" -d "Temp/StagingArea/Data/Managed" -x "tmplink.xml" current dir : Temp/StagingArea/Data/Managed

 iOS 빌드 세팅 -> Other Settings -> Optimization -> Stripping Level이 Use micro mscorlib로 되어있는데 Strip ByteCode나 Disabled로 해주면 해결이 되긴 되더군요.

 그런데 작년에 애셋번들 패치 만들면서 썼던 BinaryFormatter를 iOS에 사용하기 위해서는 Use micro mscorlib로 해줘야 했었는데 말이죠. 아무튼 LLVM과 관련된 이슈가 iOS는 아직 좀 있네요.
