Build failure: swift

[XYenon]

Swift still built failed after https://github.com/NixOS/nixpkgs/pull/326588 has been merged.

Steps To Reproduce

Steps to reproduce the behavior:

1. build swift on x86_64-darwin with nixpkgs 693bc46d169f5af9c992095736e82c3488bf7dbb

The interesting part is that I could build this locally in my laptop (macOS 14.5), but it isn't working in GitHub Actions (also macOS 14.5). Here is my logs from GitHub Actions: https://github.com/thiagokokada/nix-configs/actions/runs/9976188278/job/27567744849.

Hello swift maintainers @dtzWill @trepetti @dduan @Trundle @stephank

on the nixpkgs trunk branch, swift-unwrapped is currently failing to build on 3/4 platforms:

• https://hydra.nixos.org/job/nixpkgs/trunk/swiftPackages.swift-unwrapped.aarch64-darwin ❌
• https://hydra.nixos.org/job/nixpkgs/trunk/swiftPackages.swift-unwrapped.aarch64-linux ❌
• https://hydra.nixos.org/job/nixpkgs/trunk/swiftPackages.swift-unwrapped.x86_64-darwin ❌
• https://hydra.nixos.org/job/nixpkgs/trunk/swiftPackages.swift-unwrapped.x86_64-linux ✅

two of the above platforms (aarch64-darwin, x86_64-darwin) have been broken for 1.5 months :(

can you please take a look?

[nixos-discourse]

This issue has been mentioned on NixOS Discourse. There might be relevant details there:

[yelite]

Just a note on how I workaround this, in case it's helpful for people who reach here.

I am able to build my system with the latest unstable with swift replaced by the swift from 2e92235aa591abc613504fde2546d6f78b18c0cd (the previous commit of the first failed build of swift.aarch64-darwin https://hydra.nixos.org/build/262793523). In my setup swift is only used by mpv so YMMV.

(final: prev: let
  pkgsDarwin= import darwin-nixpkgs {inherit (prev) system;};
in
  prev.lib.optionalAttrs prev.stdenv.hostPlatform.isDarwin {
    inherit (pkgsDarwin) swift;
  })

where

    darwin-nixpkgs.url = "github:nixos/nixpkgs?rev=2e92235aa591abc613504fde2546d6f78b18c0cd";

in flake.inputs.

[aaronpkelly]

Thanks @yelite for your flakes workaround

I don't use flakes myself, so one workaround I'm using for the moment is excluding all packages that pull in swift as a dependency.

To do this:

• I generated a derivation of my next system rebuild
• looked at the dependency tree, found out which packages are pulling in swift
• excluded them from my darwin-configuration.nix
• repeated the above steps, removing packages until swift no longer appeared

Here are the commands... I generated a derivation my next rebuild by using --dry-run:

$ darwin-rebuild switch --dry-run
building the system configuration...
trace: warning: nixfmt was renamed to nixfmt-classic. The nixfmt attribute may be used for the new RFC 166-style formatter in the future, which is currently available as nixfmt-rfc-style
these 107 derivations will be built:
/nix/store/9cvhkxbx69pd8w9kw9xwcccn98bxdwc6-swift-5.8.drv
/nix/store/52bvqras0kmavb9x7mg5x2w8bjkfwwkc-swift-wrapper-5.8.drv

...
/nix/store/i37yr1qrlg15cjrv1rj5rmvsnrwh3asa-darwin-system-24.05pre634371.29e8e22b42cc+darwin4.drv

That's my next derivation there on the last line. I turned this next derivation into a dependency tree (i output it to a file so I could browse it a bit easier):

nix-store --query --tree /nix/store/i37yr1qrlg15cjrv1rj5rmvsnrwh3asa-darwin-system-24.05pre634371.29e8e22b42cc+darwin4.drv > ~/output_dependencies_next

After squinting hard at that file for a bit, it turns out that mpv, or anything that depends on mpv, will also pull in swift as a dependency. This is unfortunate because mpv is pretty incredible and I'd hate to go without it. So, I excluded mpv, and a few other packages like yt-dlp, somafmcli and curseradio.

After excluding the above, the dependency tree of my next generation didn't include swift, and I was finally able to run darwin-rebuild switch to completion

FWIW Swift is getting fixed as we speak as part of the macOS SDK rework. That’s still a few weeks out from landing in unstable, though.

swift is now failing to build on Linux. It's a transitive dependency of deadbeef (an audio player). The direct dependency is swift-corelibs-libdispatch.

The build error occurs when running swig to create Python bindings:

It’s a SWIG 4 issue; I’m working on it.

FWIW the Darwin SDK rework is not going to significantly change a lot of the problems with the Swift derivation. It’s pretty unmaintainable right now. If anyone is strongly invested in Swift, I strongly suggest trying to factor out their LLVM from the core Swift derivations. Right now it spends so much time building its own LLVM and Clang and so on. I don’t know whether the use of their specific LLVM fork is mandatory. If it isn’t, then we should just use the existing packages from Nixpkgs. If it is required, then it should at least be built with the LLVM package machinery we already have in‐tree so that we don’t have to duplicate patches and other complexity.

(This won’t fix the Darwin problems or Hydra weirdness though.)

[emilazy]

The PR has now been merged and I successfully built Swift on aarch64-linux and x86_64-darwin. Would be good to hear more build reports to see if the problem here is fixed. We still don’t know what’s up with the builds on Hydra, though.

[neilmayhew]

Works for me, using commit 418918ebb102 from master, on an x86_64-linux system.

Thanks for fixing this! :raised_hands:

[ofalvai]

Works for me as well on aarch64-darwin!

Thanks Emily, i hadn't been using swift stuff for a bit and can confirm it fixed the issues I was having on my builds.

Does hydra weirdness mean this? https://hydra.nixos.org/build/272581651/nixlog/1

[emilazy]

Yes. The hope is that Randy’s SDK rework will make it go away, but I don’t think anyone understands it. It builds successfully locally for everyone, as far as I know.

I have tried this on macOS 15.0 x86_64 and it builds failed 😭

Same failure when bumping devenv-nixpkgs: https://github.com/cachix/devenv/actions/runs/11140734654/job/30961906452?pr=1489#step:7:4516

[domenkozar]

Can someone try building swift on https://github.com/NixOS/nixpkgs/pull/346043

[reckenrode]

Can someone try building swift on #346043

Swift is definitely broken on #346043. I have a separate set of fixes for building Swift after that is merged. I’ll be opening that (and others) later today, but it won’t be able to merge until after that PR is merged.

[reckenrode]

https://github.com/NixOS/nixpkgs/pull/346947 is the follow up PR for Swift that fixes it to build with the new SDK.
