Use new .NET 6 SDK for iOS backend #7565

maxkatz6 · 2022-02-09T06:37:42Z

Build instructions

For .NET6:

Install 6.0.200 SDK
Install latest workloads (might need to delete old before):

dotnet workload install --no-cache --disable-parallel ios --skip-manifest-update --source "https://pkgs.dev.azure.com/xamarin/public/_packaging/maui-main/nuget/v3/index.json" --source "https://pkgs.dev.azure.com/azure-public/vside/_packaging/xamarin-impl/nuget/v3/index.json" --source "https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet6/nuget/v3/index.json" --source "https://api.nuget.org/v3/index.json"

Follow this guide to enable provisioning https://docs.microsoft.com/en-us/xamarin/ios/get-started/installation/device-provisioning/free-provisioning?tabs=macos
You might need to set runtimeidentifier to either "iossimulator-x64" or "ios-arm64"
Build ControlCatalog.iOS with latest Rider EAP or command line (will start first available simulator):

dotnet build -t:run

If you run from command line, you can specify simulator or real device - Figure out 'dotnet run' CLI experience for iOS and Android dotnet/xamarin#26 (comment)

We need latest/preview workloads to have this PR merged - xamarin/xamarin-macios#12572
Without that we can't have actually working HarfBuzz - mono/SkiaSharp#1879

For legacy Xamarin.iOS

Install Xamarin SDK for iOS
Follow this guide to enable provisioning https://docs.microsoft.com/en-us/xamarin/ios/get-started/installation/device-provisioning/free-provisioning?tabs=macos
Select either iPhone or iPhoneSimulator targets for the solution.
Run ControlCatalog.iOS.Legacy project

What's not working:

SkiaSharp can't create SKSurface from GRContext (solved even with latest skia)
AOT on the real device stopped working during working on this PR. Probably some of changes broke it. (works now with interpreter enabled)

src/iOS/Avalonia.iOS/Avalonia.iOS.csproj

  </PropertyGroup>
  <ItemGroup>
-    <Reference Include="OpenTK-1.0" />


OpenTK GL isn't available in net6-ios, and Xamarin team seems to migrate away from having out-of-box OpenTK, deprecating it slowly.
There is another option of having OpenTK.Graphics nuget package.
But we already have these mappings in GlInterface class used for other backends, so why not use it here.

It's sad 🙂

maxkatz6 · 2022-02-24T10:51:40Z

@rstm-sf at least it works with current IDEs.
When I started this PR net6-ios target wasn't usable at all with SkiaSharp (that has native references). It was fixed only in recent SDK update. Still there is no proper IDE support.

This is extremely fast and performant on iPad. Is iOS phones also just as fast?

I know historically Xamarin tends to work faster on iOS than Android but I still wonder how to get this level of performance on Android. Maybe the CPU is just that much more powerful on the iPad?

maxkatz6 · 2022-02-25T04:01:13Z

Is iOS phones also just as fast?

I don't have any, but before it had good performance IIRC.

I still wonder how to get this level of performance on Android

No idea. It seems new Android AOT doesn't really make it as good as .NET for iOS.

Maybe the CPU is just that much more powerful on the iPad

Well, this's iPad Pro with M1 processor. So, it's expected to be way faster than any android device currently.
