[mobile] Enable NativeAOT library tests on Apple mobile platforms by kotlarmilos · Pull Request #125437 · dotnet/runtime

kotlarmilos · 2026-03-11T12:46:57Z

Description

Enables NativeAOT library tests on Apple mobile in extra platforms by wiring the trim+ILC step on the host build leg and consuming the produced static library in AppleAppBuilder library mode on the Helix.

Build flow

Host (build leg): publishes each test project with NativeLib=Static + CustomNativeMain=true, producing lib<TestAssembly>.a plus the staged ILC link inputs. eng/testing/tests.ioslike.targets is updated to set TestNativeAot/TestSingleFile/PublishAotUsingRuntimePack and to opt into _SuppressNativeLibEventSourceWarning for the static-library path.
Helix (proxy): src/mono/msbuild/apple/data/ProxyProjectForAOTOnHelix.proj no longer re-runs ILC on the agent. It detects the prebuilt static library via the new _NativeAotLibraryTestOnHelix property, replaces _AppleNativeAotCompile in $(AppleBuildDependsOn) with _StageNativeAotLinkInputsOnHelix, and unconditionally adds DirectPInvoke __Internal so the AppleAppBuilder-generated objc symbols (mono_ios_set_summary, …) are statically resolved by ILC.

Pipelines

runtime.yml keeps the existing AllSubsets_NativeAOT_Smoke legs for iOS device + maccatalyst arm64, runs System.Runtime.Tests plus iOS functional tests.
eng/pipelines/extra-platforms/runtime-extra-platforms-{ioslike,ioslikesimulator,maccatalyst}.yml add AllSubsets_NativeAOT[_AppSandbox] legs. They run a curated subset of library tests: System.Runtime, System.Collections, System.Linq, System.Threading, System.Threading.Tasks, System.Net.Http.Functional.

Depends on dotnet/xharness#1554
Fixes #81075

Replace NativeAOT runtime test legs with library test legs on iOS/tvOS devices, iOS/tvOS simulators, and Mac Catalyst. The runtime tests (nativeaot/SmokeTests) provide minimal value on mobile since the compiler doesn't meaningfully distinguish between iOS and macOS. Library tests exercise OS-specific APIs (crypto, networking, etc.) that are the real quality gate. Changes: - ioslike: remove NativeAOT runtime test leg, update existing library test leg to use dynamic smoke test arg - ioslikesimulator: replace NativeAOT runtime test leg with library test leg, fix isiOSLikeSimulatorOnlyBuild parameter - maccatalyst: replace both NativeAOT runtime test legs (regular + AppSandbox) with library test legs, fix coreclrContainsChange variable (was incorrectly using monoContainsChange) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview

This PR updates the Apple “extra platforms” CI legs to validate NativeAOT on iOS/tvOS devices, iOS/tvOS simulators, and Mac Catalyst by running libraries tests (via Helix) instead of the minimal NativeAOT runtime SmokeTests, improving OS-specific coverage (crypto/networking/globalization) on mobile.

Changes:

Switch NativeAOT Apple-mobile legs from runtime SmokeTests submission to eng/pipelines/libraries/helix.yml submission of libraries tests.
Use eng/pipelines/libraries/helix-queues-setup.yml and pass NeedsToBuildAppsOnHelix=true for the new legs.
Update naming/args to use $(_runSmokeTestsOnlyArg) and fix path-evaluation variable naming in affected legs.

Replace the blanket .json exclusion in the NativeAOT bundler path with specific publish-metadata suffixes (.deps.json, .runtimeconfig.json, .runtimeconfig.dev.json). Content files like appSettings.json now flow through to the .app/ bundle, fixing CanConfigureAppConfigurationFromFile and similar tests in Microsoft.Extensions.Hosting.Unit.Tests on iOS, tvOS, and MacCatalyst NativeAOT. The .dll exclusion is left in place because NativeAOT publish output contains ILC intermediate .dll files that legitimately shouldn't be bundled; separating content .dll from intermediate .dll requires a broader publish-folder refactor (per the existing TODO).

The general direction looks good. I have not looked at anything under eng/pipelines, mono/, tasks/ and the tests.ioslike.targets, tests.mobile.targets, so please get a review from someone who knows what those components are.
