[BUG] Cannot build or run .Net 8 tvOS project #2947

Open munit79 opened 1 month ago

munit79 commented 1 month ago

Description

Create a new tvOS application in .Net 8, it builds and works fine. If I add a SkiaSharp reference, i.e.

<PackageReference Include="SkiaSharp" Version="2.88.8" />

Then the build fails with this error...

  ld: building for tvOS Simulator, but linking in dylib built for tvOS, file '/Users/mt/.nuget/packages/skiasharp.nativeassets.tvos/2.88.8/runtimes/tvos/native/libSkiaSharp.framework/libSkiaSharp' for architecture arm64

Expected Behavior

I'd expect the app to build and run.

Actual Behavior

It seems to want to link the wrong version of SkiaSharp, i.e. the device build rather than a simulator build.

I get a similar problem when compiling for the App Store, it builds OK, but Apple rejects the build because the skiasharp library is built for the simulator, not the device.

We were able to use SkiaSharp successfully on our Xamarin version of the tvOS app, and we can also successfully use it on the MAUI based iOS version of the app.

I suspect it will need something like this: https://github.com/mono/SkiaSharp/pull/2468

munit79 commented 1 month ago

@mattleibow Is there a timeframe for this fix? Since Xamarin won't support the later Apple SDKs, we're forced to move to .Net 8, and Skia is a major part of our app.
