swiftly 1.0.0-dev (release/1.0) can't install 6.1-snapshot

[kkebo]

Summary

swiftly 1.0.0-dev (release/1.0) can't install 6.1-snapshot. I understand that it hasn't released yet, but we need to use 1.0.0-dev on some platforms.

• Ubuntu 24.04
• Debian 12

Steps to reproduce

1. Install swiftly 1.0.0-dev

git clone https://github.com/swiftlang/swiftly
cd swiftly
git switch release/1.0
swift build -c release
.build/release/swiftly init  # and follow the instructions

1. Run swiftly install 6.1-snapshot

Expected behavior

Swift 6.1 development snapshot is successfully installed.

Actual behavior

$ swiftly install 6.1-snapshot
Fetching the latest 6.1 development branch snapshot...
Error: You have requested to install a snapshot toolchain from branch 6.1 development. It cannot be found on swift.org. Note that snapshots are only available from the current `main` release and the latest x.y (major.minor) release. Try again with a different branch.

I think this is because there is no 6.1 directory in /api/v1/install/dev.

Environment

• Ubuntu 22.04 aarch64
• swiftly release/1.0 branch 400e6a967a8f2335105d00237afef908d7240355

Thanks for reporting this. I'm not quite sure what should be done in this case. Swiftly uses the swift.org API, and if that API doesn't indicate that it's there then it can't really determine whether it can download it.

@cmcgee1024 Thank you for replying. My suggestion is to add 6.1 to the swift.org API. IIUC, it should already be possible.

I think this is because there is no 6.1 directory in /api/v1/install/dev.

@kkebo if there's nothing to be done on the swiftly side, should this issue be closed in favour of a swift-org-website issue?

Agree, this is pretty confusing given release/6.1 snapshots are listed here: https://www.swift.org/install/macos/#development-snapshots

@shahmishal do you have permission to move this issue to https://github.com/swiftlang/swift-org-website ?
