"error: Invalid bitcode signature" when linking iOS build

I've been trying to figure this error out for the last couple days... We have a native iOS plugin that we're building with Xcode (as a static lib, as required). I've tried all combinations of settings in Xcode for both the plugin and the game build, but not having any luck troubleshooting or finding info about this. Any help would be appreciated! ---------- Unity 2017.2.0f3 Xcode 9.2 ---------- I have already tried: - Enabling/Disabling bitcode on both the lib and the game via the 'Enable Bitcode' Yes/No - Ensured that both projects are targeting the same deployment target (I've tried a few -- 11.1, 9.0, 8.0)
