Try to compile for other platforms (tvOS, watchOS, visionOS, Android)

[lemonmojo]

Outdated Info (both iOS and Android are supported now):

As of May 2023, NativeAOT is only (officially) supported on desktop platforms.

Regarding iOS:
dotnet/runtime#80905

Regarding Android:
dotnet/runtime#76983

Check again in .NET 8 Preview 6

[lemonmojo]

As expected, this is a supported scenario in Preview 6: https://devblogs.microsoft.com/dotnet/announcing-dotnet-8-preview-6/
So we can test this now.

[lemonmojo]

Unfortunately it looks like NativeAOT support for iOS in .NET 8 Preview 6 is currently limited to app projects and classlibs are not supported.

@filipnavara is that correct?

The current state of the iOS experiments is here.

[lemonmojo]

Building for ios-arm64 works now with some workarounds in the csproj:

• PublishAotUsingRuntimePack needs to be set to true (This is actually documented)
• _IsAppleMobileLibraryMode needs to be set to false
• The linker must be configured to target iOS by adding this:

<ItemGroup>
    <LinkerArg Include="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk" />
    <LinkerArg Include="-mios-version-min=16.0" />
</ItemGroup>

A "dummy" (unused) Main method must be present in the .NET project that's to be compiled with NativeAOT.

Many thx for your support @filipnavara!

Btw, for the Android part, that should also work if you use the Bionic RID. This issue has the latest details: dotnet/runtime#87340. The official doc is not written up yet.

[lemonmojo]

@MichalStrehovsky Many thx for the info! I'll get to Android part once I'm happy with the way things work for Apple targets.

[lemonmojo]

dotnet/runtime#93658 will add proper iOS library support to .NET. Once that lands, we should remove the various workarounds that are in place today.

[lemonmojo]

There's hope for visionOS support: dotnet/runtime#87929
