I am getting below error when running the MAUI app on mac visual studio code:

/usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net8.0_18.0/18.0.8319/targets/Xamarin.Shared.Sdk.targets(1648,3): error : clang++ exited with code 1: [/Users/sreejith.sreenivasan/Downloads/inv-hnas337-mobile-patient/Inventiva/Inventiva.csproj::TargetFramework=net8.0-ios] /usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net8.0_18.0/18.0.8319/targets/Xamarin.Shared.Sdk.targets(1648,3): error : Undefined symbols for architecture arm64: [/Users/sreejith.sreenivasan/Downloads/inv-hnas337-mobile-patient/Inventiva/Inventiva.csproj::TargetFramework=net8.0-ios] /usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net8.0_18.0/18.0.8319/targets/Xamarin.Shared.Sdk.targets(1648,3): error :   "_swift_FORCE_LOAD$_swiftCompatibility56", referenced from: [/Users/sreejith.sreenivasan/Downloads/inv-hnas337-mobile-patient/Inventiva/Inventiva.csproj::TargetFramework=net8.0-ios] /usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net8.0_18.0/18.0.8319/targets/Xamarin.Shared.Sdk.targets(1648,3): error :       _swift_FORCE_LOAD$swiftCompatibility56$_FirebaseAnalytics in FirebaseAnalytics[arm64]17 [/Users/sreejith.sreenivasan/Downloads/inv-hnas337-mobile-patient/Inventiva/Inventiva.csproj::TargetFramework=net8.0-ios] /usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net8.0_18.0/18.0.8319/targets/Xamarin.Shared.Sdk.targets(1648,3): error :   "_swift_FORCE_LOAD$_swiftCompatibilityConcurrency", referenced from: [/Users/sreejith.sreenivasan/Downloads/inv-hnas337-mobile-patient/Inventiva/Inventiva.csproj::TargetFramework=net8.0-ios] /usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net8.0_18.0/18.0.8319/targets/Xamarin.Shared.Sdk.targets(1648,3): error :       _swift_FORCE_LOAD$swiftCompatibilityConcurrency$_FirebaseAnalytics in FirebaseAnalytics[arm64]17 [/Users/sreejith.sreenivasan/Downloads/inv-hnas337-mobile-patient/Inventiva/Inventiva.csproj::TargetFramework=net8.0-ios] /usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net8.0_18.0/18.0.8319/targets/Xamarin.Shared.Sdk.targets(1648,3): error : ld: symbol(s) not found for architecture arm64 [/Users/sreejith.sreenivasan/Downloads/inv-hnas337-mobile-patient/Inventiva/Inventiva.csproj::TargetFramework=net8.0-ios] /usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net8.0_18.0/18.0.8319/targets/Xamarin.Shared.Sdk.targets(1648,3): error : clang++: error: linker command failed with exit code 1 (use -v to see invocation) [/Users/sreejith.sreenivasan/Downloads/inv-hnas337-mobile-patient/Inventiva/Inventiva.csproj::TargetFramework=net8.0-ios]     2869 Warning(s)     1 Error(s)   Time Elapsed 00:01:15.59

My Xcode version:

xcodebuild -version

Xcode 16.4

Build version 16F6

Dotnet version:

Version: 8.0.412

Workload details:

maui-ios 8.0.100/8.0.100 SDK 8.0.400

maui 8.0.100/8.0.100 SDK 8.0.400

In my MAUI project I have added .NET class library and .NET MAUI class library project. I have alsi added a global.json to force use .NET 8 like below.

{ 
	"sdk": 
	{ 
		"version": "8.0.412" 
	} 
}

To fix the error I have added a PropertyGroup like below on my MAUI project .csproj.

<PropertyGroup Condition="'$(TargetFramework)' == 'net8.0-ios'">
        <MtouchLink>SdkOnly</MtouchLink>
        <_EnableSwiftSupport>true</_EnableSwiftSupport>
    </PropertyGroup>

None of them resolves the issue, please suggest the correct solution.
