Appears to be causing https://github.com/wieslawsoltes/Svg.Skia/issues/125

To whomever hits this, we encountered this issue on Uno Platform and the root cause of this is the fact that SkiaSharp in .NET Standard 2.0 references System.Memory in a different version and that version mismatch causes issues with ReadOnlySpan. The workaround is to add the following targets to the iOS .csproj:

<Target Name="VSMac_RemoveSystemMemory" BeforeTargets="ResolveAssemblyReferences">
  <ItemGroup>
    <_ReferenceToRemove Include="@(Reference)" Condition="'%(Reference.Identity)'=='System.Memory'" />
    <Reference Remove="@(_ReferenceToRemove)" />
    <Reference Include="System.Memory" />
  </ItemGroup>
</Target>

<Target Name="VS_RemoveSystemMemory" BeforeTargets="FindReferenceAssembliesForReferences">
  <ItemGroup>
    <_ReferencePathToRemove Include="@(ReferencePath)" Condition="'%(ReferencePath.NuGetPackageId)'=='System.Memory'" />
    <ReferencePath Remove="@(_ReferencePathToRemove)" />
  </ItemGroup>
</Target>

This really worked for me. Thank you very much. Xamarin.Forms = 5.0.0.2545 SkiaSharp.Views.Forms = 2.88.3 Svg.Skia = 0.5.18

Works like a charm, thanks!
