How to write in Swift without Mac OS?

Question

iOS

Good day to all. The situation is this: I'm learning Swift. I want to write an app for iPhone. The idea is already there. But right now there is no Macbook (to install Xcode). I read that this is the main development environment.
Questions:
How to code in Swift without Xcode? (maybe there are good analogues, etc.)
Is it possible to install Xcode on Windows?
Is it possible to program on a virtual machine? (If I put Mac OS there).
Do not judge strictly - a beginner in this matter.

You can only make programs in xcode.
But you can make hybrid applications ReactNative, Cordova, PhoneGap Xamarin.
I use a virtual machine for development https://github.com/vkorotenko/MacOSMojaveOnHyper-V
In principle, the same can be done using VirtualBox
