I’ve done some limited research, and it should be possible to build from anything if you don’t use any apple specific cpu features or frameworks etc. that being said, that will be a pretty bad experience so I assume these services require a Mac for that reason. I could be wrong about react native though, only found one questionable source that said you could.

You cannot. Both flutter and react native still requires code to build an iOS app afaik. Source: I have to do this sht sometimes at work.

The Vapor project is a good example for what you are alluding to.

Server side swift doesn’t require a Mac, just Unix.

Technically you can, but no at least mediocre framework supports it, for the thread context it seems just bike shading
