Where's the Preview Variants 😂 I can't find it where it should be

Hi,

Sorry to hear you are having problems getting the new previews variants working. Best next step will be to file a feedback with diagnostics.

We will need the diagnostics Xcode Previews generates in order to make sure we understand any issues the previews system is encountering.

Then when you get an error in Xcode Previews, an error banner appears in the canvas

1. Click the "Diagnostics" button in that banner (or if the banner is missing you can use the menu: Editor > Canvas > Diagnostics)
2. In the sheet that appears, click "Generate Report" in the bottom left of the sheet
3. Attach (or make from the folder) the resulting zip file to the bug (will be named something like previews-diagnostics-0123456789.zip)

In this case I think a screen recording of the canvas in xcode loading the preview and showing the preview would be helpful too.
