On Android (and I'm pretty sure iOS) you have WYSIWYG editors for UI layouts for jetpack compose and flutter (and on iOS it would be Swift UI).

These all go direct to code instead of XML or some other extra layer of code.

What I would probably focus on is better integration with Figma and similar tools. Use that to do the WYSIWYG part and then generate corresponding code (possibly with LLMs).

The biggest limitation you tend to have in WYSWIG is that at some point you really need to have the true data the user sees to ensure everything looks good. That becomes a bigger hassle than coding the UI manually. (Particularly when doing multi-platform things.)
