Ios build fails looking for androidruntimesettings.precompiled

trying to package a project for IOS and i get this error saying it cant find some android stuff, why the heck is it trying to find android stuff inside an IOS subfolder? and how do i fix this so it builds?

ERROR: System.IO.DirectoryNotFoundException: Could not find a part of the path 'W:\apps\Epic Games\UE_4.20\Engine\Intermediate\Build\IOS\UE4\Shipping\Android\AndroidRuntimeSettings\AndroidRuntimeSettings.precompiled'.

turns out there was a line in the build.cs causing the issue

DynamicallyLoadedModuleNames.Add("OnlineSubsystemGooglePlay");

so i guess that was trying to add the android stuff to all builds including iOS

i removed that and no longer get the issue
