Asset catalogs are not available for the iOS platform. - Build error for iOS but not Android

[DclearEE]

Hi Uno Community. I am getting an error specific to iOS and not anything else. I can build and deploy the project for Android.

During the build after the signing of the app with my paired remote Mac, I get an error:

1>Tool arch execution finished (exit code = 1).

I have assets in the "Asset" folder, organized into their own folders. All assets are set to "Build Action: Content. Copy to Output: Do not copy".
Is there something I'm missing as far as storing content for an iOS build?
For reference this is the same project from my last question I posed here: #10346

Please help me understand this error and how to fix it.
Thank you!

Thanks for the report. Can you provide a repro project for this issue?

I manage to get this error today, accidently by changing Xcode path in the settings:

VS (windows)\Tools\Options > Xamarin\iOS Settings\Apple SDK\Xcode path: `/Applications/Xcode-14.2.app` -> `/Applications/Xcode.app`

This error happens if you try to deploy/debug the ios app, but only if you dont restart visual studio after changing that setting.
The project in question is a mostly fresh unoapp ([email protected]) with only cs+xaml changes.

The problem was fixed when I switched some YAML Deserialization functions to NewtonSoft.JSON functions. And converted the YAML files to JSON files. Unfortunately I was not able to debug this problem on iOS but I was able to find the bug by debugging WASM. I think it's just a coincidence that it was the same bug.

I was using the package YamlDotNet version 12.0.2 in this project. While it was building for all platforms, only Windows and Android were able to successfully deploy and run.

That's what I get for trying to be fancy and use YAML lol. I think JSON is converted faster than YAML anyway.
