Hello! I have a ton of custom UI elements and want to extend the types on them and not sure how to do that. For instance I have a Switch component and want autocompletion on uischema.options?.props. Is there a path forward for this?

Hi @themattmayfield,

The best way forward is to use your own typeguards and assertions. I’m not sure that there is a way the framework could help you without doing the same.
