Apple went out of its way to deliberately disable physical phones connecting to a virtual MacOS. Any other USB device can be connected, but not an iphone.
It works quite well for me. Simulator works fine (though graphics are slow) and so does connecting a physical phone (by passing through the USB controller).
(yes, I'm aware of a bunch of fragile solutions involving VirtualBox, but they tend to be slowish, that's also supposed to be paid if you're using the extensions for commercial operation IIRC, and several versions of macOS/OSX remain a huge pain in the ass to set up on it regardless)
its however not permissable, as you cannot buy apple software without agreeing to their licence, which disallows running it on anything but apple hardware.
for private fun projects: possible
for professional things: a very bad idea
