The ResolveReadyToRunCompilers task fails when building for mobile platforms

[rolfbjarne]

Description

When trying to use R2R on mobile platforms, the ResolveReadyToRunCompilers task fails with:

error NETSDK1095: Optimizing assemblies for performance is not supported for the selected target platform or architecture. Please verify you are using a supported runtime identifier, or set the PublishReadyToRun property to false.

We have a workaround, so it's not urgent, but this would be nice to get fixed at some point.

Reproduction Steps

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>

    <TargetFramework>net11.0</TargetFramework>
    <RuntimeIdentifier>ios-arm64</RuntimeIdentifier>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
    <PublishReadyToRun>true</PublishReadyToRun>
    <PublishReadyToRunComposite>true</PublishReadyToRunComposite>
  </PropertyGroup>
