Add Android to platforms supported

[finagolfin]

I didn't bother with adding doc here as that's mostly about installing the toolchain natively, whereas Android is mostly cross-compiled to, so I linked to the doc on my cross-compilation SDK instead. Whenever the new cross-compilation bundles in SwiftPM are up and running, maybe we'll distribute an Android bundle from this site and then I'll add doc about using that.

For now, this is just to let people know that Android is supported and to what extent.

I have not tried building the debugger and REPL natively yet. May not matter as most will debug remotely for Android, so I believe they can use the existing toolchains' lldb to debug.

Android isn't an officially supported platform I believe right?

[finagolfin]

The previous section says Platform owners have sections on forums.swift.org and meet bi-weekly to discuss active development and open issues on the platform, but I don't think Android dev is so active yet.

I thought this page is just about what platforms the OSS codebase supports, not what Apple supports? I guess it depends what you mean by "official."

There is a native toolchain available in the Termux app for Android, which I ported and maintain, that includes SwiftPM and sourcekit-lsp. I didn't bother linking to it as most will not build natively on Android, just as Swift Playgrounds for iPadOS is not listed here.

By official I mean platforms the Swift Language Team have committed to supporting, running CI on, fixing bugs and releasing toolchains for that platform.

@shahmishal could you confirm?

PS I'm not saying this shouldn't be here, but we should probably put it in a community platform section/page

I see no mention of the word "official" with that definition in this website or docs. Indeed, the Windows port does not fulfil that definition, as it is mostly done by Saleem and @stevapple.

The fact that Windows port is official is stated on https://swift.org/download page:

Saleem is the platform champion for the Windows port of Swift and this is an official build from the Swift project.

Right, but there is no indication there of what "official" means, and the definition Tim suggested above doesn't seem to apply to that port.

Pinging @shahmishal again, wdyt?

Ping @tomerd, wdyt?

@compnerd, you last modified this page, let me know what you think.

[finagolfin]

Pinging @shahmishal again, I see that you recently submitted another pull to modify this page about linux distro support.

The "Platform Support" page contains information about the platform officially supported.

Here are key parts for including new platforms on the platform support page:

Platform Owners
Support for developing and running Swift applications on various platforms is supported by different members of the Swift open source community. Each platform has a champion, called a platform owner, that acts as the primary steward of maintaining support for a given platform.

Platform owners help facilitate contributors to the Swift project to collaborate and continue to work towards progressing a given platform. These individuals would also be able to guide porting specific changes on the platform. Platform owners have sections on forums.swift.org and meet bi-weekly to discuss active development and open issues on the platform.

Platform Review

Swift community members can propose adding new platforms to the tables by requesting a review on forums.swift.org. The Swift Core team will review such proposals.

Code Signature for Downloadable Builds

Platform owners will build and sign the toolchain before providing it to Apple. Apple will then re-sign the toolchain under swift.org certificate and distribute it on the website. The builds will only be re-signed if they are not built by Apple. There will be random audits to validate the signatures between both the platform owners and Apple.

To add Android to the "Platform Support" page, I would suggest messaging the Swift Core team (Contact via Forums) to start the review process.

I have submitted Android for approval as an official platform and plan to submit a Docker pull for an official Android CI later this month. Once that is sorted out, hopefully we can get this in.
