iOS endpoint not possible?

@Danny I know you have explained why Apple policies prevent an iOS endpoint, but can you explain it again, please? Tidal and other apps do audio output. And Audeze has some software for their Lighning DAC-cable (which I have just ordered).

An iOS Roon endpoint would suit my lifestyle really well. Currently my headphone listening is fixed to one chair…

Never mind, I just saw Brian’s answer, which I had seen before.
