but hope this will help you:

The file is located in: /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/iOS

Before:

<Target Name="_CalculateCodesignAppBundleInputs" Condition="'$(_RequireCodeSigning)' == 'true'">
        <ItemGroup>
            <_CodesignAppBundleInput Include="$(_NativeExecutable)" />
            <_CodesignAppBundleInput Include="$(_AppBundlePath)Info.plist" />
            <_CodesignAppBundleInput Include="$(_AppBundlePath)embedded.mobileprovision" />
            <_CodesignAppBundleInput Include="$(DeviceSpecificIntermediateOutputPath)Entitlements.xcent" />
            <_CodesignAppBundleInput Include="@(_BundleResourceWithLogicalName)" />
            <_CodesignAppBundleInput Include="@(_NativeLibrary)" />
            <_CodesignAppBundleInput Include="@(_Frameworks)" />
            <_CodesignAppBundleInput Include="@(_ResolvedAppExtensionReferences -> '$(_AppBundlePath)PlugIns\%(FileName)%(Extension)\_CodeSignature\CodeResources')" Condition="'$(IsAppExtension)' == 'false'" />

            <!-- Include WatchOS1 App references -->
            <_CodesignAppBundleInput Include="@(_ResolvedWatchAppReferences -> '$(_AppBundlePath)%(FileName)%(Extension)\_CodeSignature\CodeResources')" Condition="'$(IsAppExtension)' == 'true'" />

            <!-- Include WatchOS2 App references -->
            <_CodesignAppBundleInput Include="@(_ResolvedWatchAppReferences -> '$(_AppBundlePath)Watch\%(FileName)%(Extension)\_CodeSignature\CodeResources')" Condition="'$(OutputType)' == 'Exe'" />
        </ItemGroup>
    </Target>

    <Target Name="_CodesignAppBundle" Condition="'$(_RequireCodeSigning)' == 'true'" DependsOnTargets="$(_CodesignAppBundleDependsOn)"
        Inputs="@(_CodesignAppBundleInput)"
        Outputs="$(DeviceSpecificIntermediateOutputPath)codesign\$(_AppBundleName)$(AppBundleExtension)">

After:

<Target Name="_CalculateCodesignAppBundleInputs" Condition="'$(_RequireCodeSigning)' == 'true'">
        <ItemGroup>
            <_CodesignAppBundleInputs Include="$(_AppBundlePath)**\*.*" Exclude="$(_AppBundlePath)_CodeSignature\CodeResources" />
        </ItemGroup>
    </Target>

    <Target Name="_CodesignAppBundle" Condition="'$(_RequireCodeSigning)' == 'true'" DependsOnTargets="$(_CodesignAppBundleDependsOn)"
        Inputs="@(_CodesignAppBundleInputs)" Outputs="$(_AppBundlePath)_CodeSignature\CodeResources">

Warning: Do not copy the entire file, as it will break other things.
Warning 2: You should not normally modify this file, as it is Xamarin’s and can stop the build process from working if you do the wrong thing.
Warning 3: It will be replaced when you update Xamarin.
