How can I stop Xamarin from building my app with bitcode enabled?

Question

In the configurations from my iOS build, there is no option to disable bitcode. While in Xcode it is possible to set ENABLE_BITCODE=NO

I need this because my linked frameworks are not build with bitcode, and nowadays Apple does not allow half-bitcode-compiled apps anymore.

Answer 1

In your .csproj for your iOS application, search for the PropertyGroup for the release configuration that you need to turn off bit code for, i.e.:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|iPhone' ">

Within that group, see if a MtouchEnableBitcode already exists and edit it, otherwise add:

<MtouchEnableBitcode>false</MtouchEnableBitcode>

Answer 2

I am able to build the application with bitcode disabled by adding following lines to the iOS app project's .csproj file immediately before the closing </Project> tag.

<Target Name="BeforeCodesign">
  <Exec Command="$(_SdkDevPath)\Toolchains\XcodeDefault.xctoolchain\usr\bin\bitcode_strip %(_Frameworks.FullPath) -r -o %(_Frameworks.FullPath)" />
</Target>

My team and I have done what Vittal Pai and SushiHangover suggested but we faced another error:

Command "\Applications\Xcode.app\Contents\Developer\Toolchains\XcodeDefault.xctoolchain\usr/bin\bitcode_strip PathToOurFrameWorks -r -o PathToOurFrameWorks" ended with code 3

^ It's translated from French so please don't bite me too hard :)

The only way we made it work was by importing the project from our GitHub to a Mac with VS 2017 and then rebuilding it there.

The error is still present on the Windows version but it's gone on the Mac version.
