Darko has very helpful videos. This one demonstrates a method to connect an Apple iPhone or iPad to a USB DAC using Apple’s Lightning-to-USB adapter.

I am not aware of an audiophile streaming device that allows the option of installing the Apple Music app. Therefore, to play Apple Music, one needs a device that runs the app or the Apple Music web browser (https://music.apple.com/us/browse). Devices can be: iPhone, iPad, Android phone, Android tablet, Mac or PC computer.
Another option, as you know, is Airplay from a compatible device to an Airplay enabled streamer.
I use a Mac mini as a server/streamer that’s connected to my DAC via USB, and wirelessly via WiFi/LAN. I rarely listen via USB, however. Most of my listening is via WiFi/LAN since my DAC has a network card. If I wanted to use Airplay, then I could use Roon, although I never use this method either...but it’s available.
