even I added this config, it also did not work:

<PropertyGroup Condition="'$(RuntimeIdentifier)' == 'iossimulator-arm64'">
    	<RuntimeIdentifier>iossimulator-arm64</RuntimeIdentifier>
	</PropertyGroup>

	<PropertyGroup Condition="'$(RuntimeIdentifier)' == 'iossimulator-x64'">
    	<RuntimeIdentifier>iossimulator-x64</RuntimeIdentifier>
	</PropertyGroup>

Please provide an MSBuild binlog, this will show much more information from the build.

Hi @rolfbjarne here is the binlog, btw a question about https://live.msbuildlog.com/ , why I cannot see the log with this exception in this website, any idea, thanks

[jingliancui]

Interesting thing:

Code can be run in x64 simulator which is only shown in vs code Uno extension with below setting, but still the same compile error with arm simulator.

	<PropertyGroup Condition="'$(RuntimeIdentifier)' == 'iossimulator-arm64'">
    	<RuntimeIdentifier>iossimulator-arm64</RuntimeIdentifier>
	</PropertyGroup>

	<PropertyGroup Condition="'$(RuntimeIdentifier)' == 'iossimulator-x64'">
    	<RuntimeIdentifier>iossimulator-x64</RuntimeIdentifier>
	</PropertyGroup>

But what make me confuse is xcode and vs code maui extension has no indicator about arm or x64:

This is because the website needs to be updated to understand newer binlog formats unfortunately.

In any case I believe this is because you're building for arm64 in the iOS simulator (RuntimeIdentifier=iossimulator-arm64), but these xcframeworks don't contain code for the arm64 iOS simulator. You'll have to contact the vendor of these xcframeworks to get an updated version that contains arm64 simulator code.

You can force the x64 simulator by adding something like this to the csproj:

<PropertyGroup>
   	<RuntimeIdentifier>iossimulator-x64</RuntimeIdentifier>
</PropertyGroup>

but note that this will interfere with any device builds you might make.

Can you try this and see if it works?
