I'm getting the same error when trying to run Comet Maui: Build FAILED.

/usr/local/share/dotnet/sdk/6.0.401/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(430,5): error NETSDK1112: The runtime pack for Microsoft.Maui.Core.Runtime.ios was not downloaded. Try running a NuGet restore with the RuntimeIdentifier 'ios'.

I've tried adding the Nuget packages (Microsoft.Maui.Essentials.Runtime/Controls.Runtime/Core.Runtime) in Visual Studio for Mac but then I'm getting an error saying that the package isn't compatible with "dotnetplatform".

#272 this PR will fix this. Update .net6 workload to 6.0.541. remove obj and bin folder and rebuild the project should work
