[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.
