Can anyone build _1password-cli on current nixos-unstable on aarch64-darwin? I'm getting errors while generating the shell completions which I'm not totally sure are actually the derivation's fault. I unfortunately don't have another Mac at hand to test.

The full error suggests permission errors around the build directory, which I wasn't able to verify. I inserted an id -u and ls -la $TMPDIR to check. On older nixpkgs, I was able to build v2.31.1 (current is v2.32.0), but simply downgrading the sources for the derivation does not resolve the issue. It would seem something has indeed changed around the sandbox, but I'm not sure where else to look.

I'm also trying to bisect, but there's a lot of building LLVM that's taking a bit of time.

samasaur: have you solved cpp interop?

In reply to @reckenrode:matrix.org
The goal right now should be to get enough of a Swift working for 25.11 with the focus being on 6.2 (and newer) for 26.05.

i figured i should make sure that the cxx interop example builds with a non-nixpkgs setup so I've been testing that. it works with swift 6.2 from Xcode. then i figured i should try swift 5.10.1, so I got it via swiftly and tried that, only to get the following error:

Building for debugging...

Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace.
