How does MtouchInterpreter property get used by these targets?

[NickDarvey]

The AOTCompile task is failing for me as described in microsoftgraph/msgraph-sdk-dotnet#1530

I'm trying to use the workaround as described in:

• xamarin ios release package cannot launch #17981 (comment)
• Mono interpreter dotnet/docs-maui#1438 (comment)

However, my MtouchInterpreter property is not having an effect and I'm trying to diagnose why.

I can see in my binlog that this property is never used (except for me declaring it) and the only place I can see that property used in this repo is

xamarin-macios/msbuild/Xamarin.Shared/Xamarin.iOS.Common.targets

Line 261 in 2606b23

Interpreter="$(MtouchInterpreter)"

which is in a target which has a condition which is not met (because UsingAppleNETSdk == true).

xamarin-macios/msbuild/Xamarin.Shared/Xamarin.iOS.Common.targets

Lines 218 to 219 in 2606b23

	<Target Name="_CompileToNative" DependsOnTargets="$(_CompileToNativeDependsOn)"
	Condition = "'$(IsAppDistribution)' != 'true' And '$(UsingAppleNETSdk)' != 'true'"

Where is the MtouchInterpreter property actually used?

For .NET projects, the $(MtouchInterpreter) property is consumed in the Xamarin.Shared.Sdk.targets file:

xamarin-macios/dotnet/targets/Xamarin.Shared.Sdk.targets

Line 487 in 2606b23

Interpreter=$(MtouchInterpreter)

However, please file an issue about the crash as well, because the AOT compiler shouldn't crash like that.
