Issue Description:

It would be really nice to be able to use Swift for Android on OS X. Considering the origins of Swift, it seems almost absurd that we have to use Linux to develop Swift on Android.

I agree 🙂

By the way, there's lots of prior discussion on this topic here: SwiftAndroid#13

Sent a pull request for support for building the runtime: #4972

I noticed that @modocache's pull request was merged. Is this issue fixed now? If so it would be really helpful to update the documentation in docs/Android.md.

v.gorlov (JIRA User) has made this work, but I don't think all his patches have been upstreamed yet.

Comment by Vlad Gorlov (JIRA)

@buttaface In one of the custom toolchain releases (about 3 month ago), the Swift source code (and also Foundation and Dispatch sources) were built without using patches. But than the situation changed again :0

IMO: This is seems what we need to do in order to have reliable "Swift Android" builds on macOS:

1. Integration of ICU, curl, SSL, XML forks into Swift sources.

2. Updating build scripts.

3. Integrating into CI (macOS).

4. Add "Swift Android" macOS target to CI checks for PRs.

This has worked well for years, closing.
