When building a Xamarin iOS application that I am in the process of migrating to the Unified Xamarin API, I am seeing a build error during the AOT phase of compilation. Error I am seeing is "Could not AOT the assembly" followed by the assembly name. I am building in Debug mode for a device (although I'm currently only building with support for the ARMv7 architecture).

The assembly that is failing to AOT compile is a binding DLL which I have written for a native 3rd party iOS library (which is proprietary, so unfortunately I cannot share it). The binding project DLL is included in a library, which is nuget packaged and installed in my Xamarin iOS application.

I have searched for this error and found a bunch of Xamarin forum posts and bugzilla entries and have tried most of the steps suggested including:

I've run a build with "-v -v -v -v" as additional mtouch arguments as suggested in several forum posts and attached the build log. I've also attached the system info from Visual Studio and Xamarin Studio on the Mac.

You mention that you have Tried link all assemblies and link SDK assemblies only --> Have you tried the Don't Link option. Does that one work? If that works, try adding --linkskip=MyCompany.IngenicoBinding to the Additional mtouch arguments field in the iOS Project Options under iOS Buildpnavk

The build log says this:

Structure field of type SByte[] can't be marshalled as LPArray

The assembly in question has a structure with an SByte[] field and no [MarshalAs] attribute (which means it will be marshaled as an LPArray, which is the default).

That scenario isn't supported by the AOT compiler, so AOT compilation fails.

This must be fixed by the library vendor.
