What is the UTType for CSS files?

Question

I am trying to use the Xamarin.Essentials FilePicker to let the user select a CSS file. My code:

Code Block var customFileType =
         new FilePickerFileType(new Dictionary<DevicePlatform, IEnumerable<string>>
           {
                    {DevicePlatform.macOS, new[] {"css"} }
            });
var pickResult = await FilePicker.PickAsync(new PickOptions
{
       FileTypes = customFileType,
       PickerTitle = "Select stylesheet to install"
});

The above works fine when I build for MacOS platform. I am also trying to add a entry there for DevicePlatform.iOS but I do not know the string to pass for a CSS file or it's UTType. I found one for HTML but not CSS.

Thanks.

The correct type is public.css.

One easy way to work this out is with the shiny new UniformTypeIdentifiers framework:

Code Block  let tQ = UTType(filenameExtension: "css")
print(tQ)
// prints: Optional(<UTType 0x109149770> public.css)

You don’t want to do that at runtime (see the Warning box in the docs) but you can build a tiny little tool that runs this code on your Mac.
