Create a conda-forge recipe (via staged-recipes) for the osx-only Swift package apple/container, including a MACOSX_SDK_VERSION: 26 variant, while working on a linux-aarch64 system that cannot build osx packages.
- +0Prompt · +0Make a conda-forge recipe for apple/container, osx-only, with MACOSX_SDK_VERSION: 26 in conda_forge_build.yaml. I'm on linux-aarch64 so I'll build and report results.
- +0mAgent did · +0mRead the conda-forge skill docs, cloned apple/container, inspected BUILDING.md, Package.swift, license/notice, and determined it's a Swift 6.2 project needing macOS 26, with latest release 1.0.0.
- +0mAgent did · +0mResearched how conda-forge handles Swift builds, SDK pinning, and the correct variant filename (conda_build_config.yaml, not conda_forge_build.yaml), inspected plugin install-path discovery logic, computed sha256, and checked package name availability.
- +8mAgent did · +8mWrote recipe.yaml, build.sh, and conda_build_config.yaml for recipes/apple-container using rattler-build v1 schema with MACOSX_SDK_VERSION: '26'.
- +8mAgent did · +8mRendered the recipe for linux-aarch64 (correctly skipped) and osx-arm64, traced through build_all.py to confirm MACOSX_SDK_VERSION propagation, and ran conda-smithy lint, which passed cleanly.
- +9mOutcome · +9mRecipe files created and lint-passing; developer's real build reported a failure in the install step (BSD install lacking -D support) after a successful 260s Swift build; agent fixed build.sh with an install_file helper and asked for a re-run.
Next time I'd tell it up front that macOS ships BSD install, not GNU coreutils, since that's the kind of platform detail it can't discover just by reading the recipe skill and docs. The actual build/render/lint work was solid and well-researched, but the real bug only showed up once I ran the build myself on macOS and reported the error back. Giving it the actual build log was what let it fix the install step correctly on the first try.
