Apparently Visual Studio messed up some files.
Attempting to extract the nupkg into the packages folder myself:

I successfully worked around this by manually adding to packages.config
and manually referencing from the fsproj file.
Packages.config:
<package id="SkiaSharp" version="1.68.0" targetFramework="xamarinios10" />
<package id="SkiaSharp.Views" version="1.68.0" targetFramework="xamarinios10" />
<package id="SkiaSharp.Views.Forms" version="1.68.0" targetFramework="xamarinios10" />
fsproj:
<Reference Include="SkiaSharp">
<HintPath>..\packages\SkiaSharp.1.68.0\lib\Xamarin.iOS\SkiaSharp.dll</HintPath>
</Reference>
<Reference Include="SkiaSharp.Views.Forms">
<HintPath>..\packages\SkiaSharp.Views.Forms.1.68.0\lib\Xamarin.iOS\SkiaSharp.Views.Forms.dll</HintPath>
</Reference>
<Reference Include="SkiaSharp.Views.iOS">
<HintPath>..\packages\SkiaSharp.Views.1.68.0\lib\Xamarin.iOS\SkiaSharp.Views.iOS.dll</HintPath>
</Reference>
Do we know for sure that the same package version worked in 16.0 and 15.9? Or was it perhaps an earlier package version?
It doesn't repro in VS 16.0 (Version 16.0.5 Preview 1.0 [28803.514.d16.0])
As of VS16.1.5, issue only repros on F# Xamarin Android projects. Nope.
I had the same issue till VS 2019 16.3 Preview 1
The only workaround was to remove all references to NuGet packages in fsproj
and execute Update-Package -project <project name > -reinstall
