I've noticed a few problems effecting my projects:

- background indexing barely works
- the `.swift-version` file not doing anything
- unit tests crashing if a `#require` throws an error with a custom comment
- excessive recompilation of the project and dependencies

I have to go back to 6.0.3 and uninstall 6.1 to get Swift usable.

My setup:

- Arch Linux: 6.13.8-arch1-1
- Swiftly: 1.0.0
- VS Code: 1.98.2
- Swift: 6.1, 6.0.3

That's weird, because I've noticed that Swift 6.1 works better for me on Ubuntu 24.04 and AlmaLinux 9 (RHEL 9) than 6.0.3 did. I'll have to check the #require thing tho since I've never used it...

> - the `.swift-version` file not doing anything

Can you elaborate more on this part? Do `swiftly use` and `swift --version` report 6.1 when the `.swift-version` file is set to `6.1.0`?

After doing more research (on the swiftly's readme) it turns out you need to manually remove previous swiftly data on the file system when upgrading to 1.0.0, which I did not do as I use the AUR (and Arch isn't officially supported). Swiftly and toolchain hot switching (and the `.swift-version` file) now works as expected, but the VS Code Extension no longer works (more specifically the sourcekit-lsp and CodeLLDB). Looks like I need to try other versions of Swiftly instead of `ubuntu24.04`, or do some tinkering.
