If I understood the motivation for this PR correctly, hybrid globalization is the new default for iOS-like platforms. However, these lines will include System.HybridGlobalization.Native library only if HybridGlobalization=true.

What are the expectations on where HybridGlobalization MSBuild property would be set?

Motivation of this PR is to support our ICU libs on Apple platforms (as currently that is not possible).
By these changes we are creating 2 separate libraries

  • System.Globalization.Native - this will include our ICU libs
  • System.HybridGlobalization.Native - this is only for Hybrid mode, using native implementations for globalization

Hence System.HybridGlobalization.Native library will be included only if HybridGlobalization=true.
If HybridGlobalization=false we will include System.Globalization.Native which is getting globalization data using our ICU libs.

I see, thank you for the explanation.

However, I am still confused with:

we only support hybrid mode on Apple platforms

Does that mean that in this new default setting, we should start linking against System.HybridGlobalization.Native by default?
And if that is the case, then HybridGlobalization=true would have to be set somewhere early in SDK

Default mode is implemented such that if the user does not enable Invariant mode, the Hybrid mode is automatically enabled. (see https://github.com/dotnet/runtime/pull/97216/files#diff-2884e8c39a88d26cb57ef06adca164f61238c4ad1c593d8e38bcb167212faa38R18 and https://github.com/dotnet/runtime/pull/97216/files#diff-45555715c5a7b53d8311327e5515c313f9e1c316f612af23fb84b5859a5c48ccR479).

If user wants to use ICU libs then they need to disable HybridGlobalization.

the Hybrid mode is automatically enabled

It is not how this build logic works. If the user does not set Hybrid mode explicitly by setting the HybridGlobalization to true, this build logic is going to default to ICU.

Right, it is how it should work; but it is not what https://github.com/dotnet/runtime/pull/97216/files#diff-a8c821001409a0c4d6589a59e663d4d07e53b0127b345f17640410828c580b37R118-R119 does.

When the HybridGlobalization property is not set, '$(HybridGlobalization)' == 'true' is going to be false and it is going to default to ICU.

For clarification: MsBuild properties have 3 states, true, false, undefined. When the property is not set then it's not false, it's undefined.

The intent is to default to hybrid. That may mean setting the value explicitly to true or defining another setting to enable icu in the sdk.

When the HybridGlobalization property is not set, '$(HybridGlobalization)' == 'true' is going to be false and it is going to default to ICU.

I see, I will change this part to check if '$(HybridGlobalization)' == 'false' or '$(HybridGlobalization)' != 'false'.

I would like to say that the improvements which hybrid globalization is bringing to both Mono and NativeAOT on iOS are amazing, and thanks @mkhamoyan and the whole team for your hard work and making this possible!

The remark I made on these lines of code seem to match the intended behaviour with the latest commit. However, I think this is only one piece of the puzzle which solves only the NativeAOT builds.

HybridGlobalization as a feature switch

As I mentioned in my comment, I think that for changes like these, when we are potentially breaking our internal and/or external customers, a better approach would be to first introduce a MSBuild property "feature switch" (for example in https://github.com/dotnet/sdk) which would be HybridGlobalization=false at first.
After that, do the implementation and make all the required changes in all our relevant repositories (dotnet/runtime, xamarin/xamarin-macios, dotnet/maui) taking into account this new features switch and test internally with HybridGlobalization=true as the changes flow in (this would potentially get better with dotnet/dotnet, but we are not there yet).
If everything works, throughout our whole stack (E2E testing passes), then simply flip the switch in the dotnet/sdk to true and announce it is the new default.
This could still break our external customers, but at least internally we made sure that we provided ways to integrate and adapt to the new change.

On the other hand, regarding questions around Mono components and their build integration #97216 (comment), this seems to be a different use case.
For Mono native components like: hot_reload, debugger, diagnostics_tracing, marshal-ilgen Mono provides both: an empty native lib version - "stub" (when the component is not needed/used) and the actual native lib with the implementation.
To toggle between what needs to be linked with the final app and to enable other build systems to specify which components should be included in the build Mono provides -> RuntimeComponentManifest.targets
and item groups: _MonoRuntimeComponentDontLink and _MonoRuntimeComponentLink.
Xamarin already implements this through: https://github.com/xamarin/xamarin-macios/blob/282d107a02d80e04a1eca780f022966d52c50215/dotnet/targets/Xamarin.Shared.Sdk.targets#L442-L461

This is a great approach, but the changes introduced here do not seem to fit. We will have two globalization libraries that we ship, but we need to link only against one of them, and according to: https://github.com/xamarin/xamarin-macios/blob/282d107a02d80e04a1eca780f022966d52c50215/dotnet/targets/Xamarin.Shared.Sdk.targets#L1134-L1141
with this PR, we would probably end up in build failures, as we would be linking against both: System.Globalization.Native and System.HybridGlobalization.Native.
This is where a global sdk-level feature switch would play a role, as the build systems (internal or external) would have a single source of truth and know which library to link against.

Another way to provide native dependencies

One thing to note is that NativeAOT also supports native components and switching them on and off (libeventpipe-enabled/disabled, libstandalonegc-enabled/disabled), but the NativeAOT build system resolves this on its own, and can provide native linker switches and dependencies for integrators to utilize and expand upon:

runtime/src/coreclr/nativeaot/BuildIntegration/Microsoft.NETCore.Native.Unix.targets

Lines 114 to 122 in 64204a5

<ItemGroup>
<NativeLibrary Condition="'$(IlcMultiModule)' == 'true'" Include="$(SharedLibrary)" />
<NativeLibrary Condition="'$(NativeLib)' == '' and '$(CustomNativeMain)' != 'true'" Include="$(IlcSdkPath)libbootstrapper.o" />
<NativeLibrary Condition="'$(NativeLib)' != '' or '$(CustomNativeMain)' == 'true'" Include="$(IlcSdkPath)libbootstrapperdll.o" />
<NativeLibrary Include="$(IlcSdkPath)$(FullRuntimeName).a" />
<NativeLibrary Include="$(IlcSdkPath)$(EventPipeName)$(LibFileExt)" />
<NativeLibrary Include="$(IlcSdkPath)$(StandaloneGCSupportName)$(LibFileExt)" />
<NativeLibrary Condition="'$(LinkStandardCPlusPlusLibrary)' != 'true' and '$(StaticICULinking)' != 'true'" Include="$(IlcSdkPath)libstdc++compat.a" />
</ItemGroup>

This approach is also supported by the Xamarin build system: https://github.com/xamarin/xamarin-macios/blob/282d107a02d80e04a1eca780f022966d52c50215/dotnet/targets/Xamarin.Shared.Sdk.targets#L1357-L1362

As the hybrid globalization change is a bit unique (and maybe in the future we will figure their would be a new implementation of say: System.Security.Cryptography.Native.Apple) we might want to provide the way for Mono to also resolve the native dependencies on its own (similarly to how NativeAOT does it) for example in: Microsoft.NET.Runtime.MonoTargets.Sdk https://github.com/dotnet/runtime/blob/64204a583ec9563b67b4e9d06538bbf46dcb29ca/src/mono/nuget/Microsoft.NET.Runtime.MonoTargets.Sdk/Microsoft.NET.Runtime.MonoTargets.Sdk.pkgproj package where RuntimeComponentManifest.targets already lives and is provided with workload installation. This way we would simplify the build integrations process altogether and make a first step towards having a runtime-agnostic integration.

These are my two cents, and please let me know if I can help in this effort to unblock the feature getting into the upcoming releases, as it brings great size saving for our customers targeting iOS platforms.
