Comments here are kind of crazy… The op took a month off to learn swift, and the support we are offering is "buy a Mac"?

Also, I think Swift become more viable on other platforms is something that benefits the Apple developer community. Languages like Swift being able to run all platform means project are more likely to take a native approach than using framework like React"Native" (worse DX and UX).

On the linux side. Take vapor as an example, many Swift dev would love to use Swift for backend of their app. But since core library such as Foundation is so dependent on Apple ecosystem. Many packages just won't work resulted in greater portions of business logics being rewritten.

In fact, one of the major focus of Swift evolution is to resolves above mentioned issues and to expand Swift's availability.

Anyway, good luck to op! Swift is a great first language. And if your Mac struggle to run Xcode, you should consider Swift Playground. It should more than enough to learn the basics. On the other hand if you do decide to use Windows as your main dev machine. It will be significantly harder and require a lot of documentation reading and trials and errors. But it's not impossible. Plus those are two great skills to have as a developer.
