As stated in the title, I am getting the following linking error when attempting to compile a Xamarin.Forms app for IOS. I am developing on Visual Studio for Windows and using a MacBook for compilation.

Compiling on the Mac directly using VS 2017 works. The application deploys and runs on the IPhone Simulator. I am using the exact same configuration. However I get the following warnings which I believe are consistent with the error messages above.

I have tried changing the supported architecture through visual studio, no luck.
I am guessing the compilation process on the MAC is providing certain arguments allowing for the build to occur regardless. Any suggestions on documentation or ideas on the subject are appreciated.
Has not been tested on the actual device yet.
The files in question at Users/vvp/Library/Caches/Xamarin/mtbs/builds/RT.iOS/9bd34334c2bb0c14c8bdf794fb67e9fc/framework' on the MAC which do exist are: ArcGIS-sim: a dynamically linked shared library i386 ArcGIS-sim64: a 64-bit dynamically linked shared library x86-64
However ArcGis-arm appears not to be present (it is a available on my windows machine not Mac).
Additionally, I am receiving the following error in my IOS project file, although I have confirmed the file in question is there.
<Error Condition="!Exists('..\..\packages\Esri.ArcGISRuntime.Xamarin.iOS.100.1.0\build\Xamarin.iOS10\Esri.ArcGISRuntime.Xamarin.iOS.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\..\packages\Esri.ArcGISRuntime.Xamarin.iOS.100.1.0\build\Xamarin.iOS10\Esri.ArcGISRuntime.Xamarin.iOS.targets'))" />
Visual studio 16 was lacking the latest update.
I should have realized this but the file locations were just different.
Updating visual studio and xamarin solved the issues.
