Yep I am also looking for a U1 to Makerfabs example.
Estimote provide an example IoS UWB app with an SDK to integrate their UWB product into your own IoS apps. The Estimote UWB beacons uses a DW3210 chip, which is a variant of the Qorvo chip used in the Makerfabs ESP32 UWB DW3000.
I believe that both chips use identical communication schemes. So in theory one should be able to provide clues to working with the other. Meaning that we should be able to create an example IoS app that connects to the Makerfabs DW3000 board.
Useful links:

YouTube tutorial for the Makerfabs DW3000 board
*Makerfabs ESP32 DW3000 Arduino Lib - The Estimote UWB app on the Apple App Stote. TLDR, its crap.
- The Estimote UWB app SDK
- The Estimote IoS Tutorial
There is also this. But I have not looked at it.
Hope this helps ... If anyone makes any progress please share ...
Also it looks like Apple is going to move from a 2 antenna U1 chip which provides an azimuth and distance, to a single antenna chip (in the iPhone 14) which does not provide the azimuth .. only giving us distance, which is a shame ... I presume its to do with security / stalking issues with the Airtag ... But who outside of Apple really knows!!?!
