    Good Afternoon,

    After upgrading my project to Unity 2019.1.6f1, the following Xcode build errors appeared:

    arm64 function not 4-byte aligned: _unwind_tester from /Users/tiagoalves/sarah-hacker-club-2nd-game-aio/Sarah-Hacker-Club-2/SHC2/Libraries/libiPhone-lib.a(unwind_test_arm64.o)
    Undefined symbols for architecture arm64:
    "__monodroid_getifaddrs_init", referenced from:
    il2cpp::icalls::System::System::Net::NetworkInformation::LinuxNetworkInterface::InitializeInterfaceAddresses() in libil2cpp.a(External_il2cpp_il2cpp_libil2cpp_icalls_System_System.Net.NetworkInformation_0.o)

    "__monodroid_freeifaddrs", referenced from:
    il2cpp::icalls::System::System::Net::NetworkInformation::LinuxNetworkInterface::FreeInterfaceAddresses(long) in libil2cpp.a(External_il2cpp_il2cpp_libil2cpp_icalls_System_System.Net.NetworkInformation_0.o)

    "__monodroid_getifaddrs", referenced from:
    il2cpp::icalls::System::System::Net::NetworkInformation::LinuxNetworkInterface::GetInterfaceAddresses(long*) in libil2cpp.a(External_il2cpp_il2cpp_libil2cpp_icalls_System_System.Net.NetworkInformation_0.o)
    ld: symbol(s) not found for architecture arm64
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

    Already tried to change architecture ARM64 to Universal, changing from IOS 11 to IOS 12, enabling and disabling Bitcode, delete the build project and rebuild it but with no success.

    For information, I'm using Firebase SDK with the most updated CocoaPods.

    Before I was using 2018.3 Unity Version.

    Same error over here while updating from 2017.4 to 2019.1.8
    Is there a solution?

    Undefined symbols for architecture armv7:
