I have a nice setup on my Linux for iOS apps. I compiled the OSXCross toolchain, and also copied iPhoneOS.sdk and iPhoneSimulator.sdk from the macOS VM. With some wrappers, I can compile iOS apps (Obj-C) on my Linux machine, sign them with zsign, and use go-ios to install them on the device.

At first, I just used simulator builds to test (and debug) on the macOS VM, in the simulator, but that was slow and painful. Finally, I bought a used iPhone, all bruised, just so I could test it on a real device. The main issue for me was signing, one cannot register a macOS VM (maybe with some kext hacks?), I managed to enable developer mode on the phone (crazy process, but it worked with Xcode in a VM), I registered the phone on the website, and paid those damn 99$.

I used that for my cross-platform UI library with native controls, based on IUP. Now, future users of the UI toolkit do not need to care about Mac, iOS, or tooling; it just works. You can check the toolkit (WIP) here https://github.com/gen2brain/iup-go .
