Code has to be at least ad-hoc signed.

It seems we're not signing nested frameworks.

@juepiezhongren Thank you for your report!

As a workaround, use this in your yourapp.csproj, you will need to accommodate the path to your needs.

Add after:

<Import Project="$(MSBuildExtensionsPath)\Xamarin\iOS\Xamarin.iOS.CSharp.targets" />

the following:

<Target Name="BeforeCodesign">
    <Exec Command="\usr\bin\codesign -v --force --sign $(_CodeSigningKey) --timestamp=none $(ProjectDir)/$(AppBundleDir)/Frameworks/UmbrellaFramework.framework/Frameworks/SubFramework.framework/SubFramework" />
</Target>

If you have multiple nested frameworks, just duplicate the Exec step as many times as needed.

Thanks. And I add Condition=" '$(Platform)' == 'iPhone', because this problem only found on iphone device.
