You could probably use Emacs for Swift...just like for about every other language.

Whether you still must download a monstrosity is left as an exercise for the reader.

I'm using flutter and had to download xcode to build the app so I guess it's a necessary step.

		I'm using flutter too, I've found a website called codemagic, so I can make builds for iOS. My laptop is windows. The bulk of development is building for Android.
