Is it possible to install Mac OS on Windows and build for ios?

Question

iOS

If you install MacOS on a virtual machine, is it possible to build a build for ios? For example a Unity build (although these guys have a cloud build), React Native or Flutter?
Are there adequate ios emulators?
Who really solved this problem and how is it? How much memory is really needed for stable operation?

Answer 1

1. You can create a build, but the application will not have a signature to place in the AppStore.
You are going to install not a full-fledged macOS, but Hackintosh, some of the functions of which do not work (this is not Windows for you to give the full functionality to pirates).
2. There is only one emulator for iOS - in the XCode package. Why didn't he please you?
3. What hardware is on the PC / laptop?
About 4 years ago I installed a Hackintosh virtual machine on a laptop from Asus. Installed on VMWare. I allocated 4GB of RAM, I only had 6 RAM. The CPU i5 was 2x nuclear - it gave 2 cores to the virtual machine.
Only the standard iOS emulator in macOS worked without lags - "installed a virtual machine to run a virtual machine on it." If you opened only XCode or another application with a similar load - wild brakes.
4. For us, who works on Unity sits on Windows. You need to build a build for iOS - they change to Mac mini.
