@rmarinho do you know who should look into these API changes?

/Users/builder/azdo/_work/2/s/src/Core/src/ImageSources/iOS/ImageSourceExtensions.cs(21,49): error CS8604: Possible null reference argument for parameter 'attributes' in 'CGSize NSStringDrawing.GetSizeUsingAttributes(NSString This, UIStringAttributes attributes)'. [/Users/builder/azdo/_work/2/s/src/Core/src/Core.csproj::TargetFramework=net8.0-maccatalyst]
/Users/builder/azdo/_work/2/s/src/Core/src/Platform/iOS/LabelExtensions.cs(88,74): error CS8601: Possible null reference assignment. [/Users/builder/azdo/_work/2/s/src/Core/src/Core.csproj::TargetFramework=net8.0-maccatalyst]

This only has catalyst, I'm manually updated the other platforms.

I found the builds with:

So then need to run darc update-dependencies --id 163188 for each of these.

/azp run

[azure-pipelines]

Azure Pipelines successfully started running 2 pipeline(s).

Going to merge this one into the Android bump: #12520

I think we have to do them both at the same time, due to the errors I'm seing now.
