This is a new packaging of the Darwin SDK. Instead of splitting libraries and frameworks into separate packages, it provides a single package for the whole SDK. # Features - Vendored files are removed from the SDK. There are 50+ different packages that are vendored by upstream (depending on the version); - Components that are built in nixpkgs (either from upstream or from the source releases) are also removed. If they need to be included by default, they are propagated; - A single SDK pattern is used to package all SDKs, and scripts are provided to aid updating the SDK version and its source release versions. This makes adding new SDKs much easier; - SDK overrides are handled by adding the SDK version you require. If multiple SDKs are present, only the newest is used. It is possible to have different SDKs for each of build, host, and target platforms; - Private headers are no longer provided by default unless you use the SDK’s `privateFrameworksHook` to add them. It does the right thing when multiple SDKs are in your inputs; - Source releases for the SDK version are available via a passthru `sourceRelease` function. This is mostly useful for getting private headers for building source releases in the darwin attrset; and - The same versions of propagated components are used on both platforms (e.g., the same libresult, libiconv, etc). See `pkgs/by-name/ap/apple-sdk/README.md` for details on how the SDK derivation is structured and how to update it.
Nixpkgs is a collection of over 100,000 software packages that can be installed with the Nix package manager. It also implements NixOS, a purely-functional Linux distribution.

Other Project Repositories
The sources of all official Nix-related projects are in the NixOS organization on GitHub. Here are some of the main ones:
- Nix - the purely functional package manager
- NixOps - the tool to remotely deploy NixOS machines
- nixos-hardware - NixOS profiles to optimize settings for different hardware
- Nix RFCs - the formal process for making substantial changes to the community
- NixOS homepage - the NixOS.org website
- hydra - our continuous integration system
- NixOS Artwork - NixOS artwork
Continuous Integration and Distribution
Nixpkgs and NixOS are built and tested by our continuous integration system, Hydra.
- Continuous package builds for unstable/master
- Continuous package builds for the NixOS 24.05 release
- Tests for unstable/master
- Tests for the NixOS 24.05 release
Artifacts successfully built with Hydra are published to cache at https://cache.nixos.org/. When successful build and test criteria are met, the Nixpkgs expressions are distributed via Nix channels.
Contributing
Nixpkgs is among the most active projects on GitHub. While thousands of open issues and pull requests might seem a lot at first, it helps consider it in the context of the scope of the project. Nixpkgs describes how to build tens of thousands of pieces of software and implements a Linux distribution. The GitHub Insights page gives a sense of the project activity.
Community contributions are always welcome through GitHub Issues and Pull Requests.

Donations
The infrastructure for NixOS and related projects is maintained by a nonprofit organization, the NixOS Foundation. To ensure the continuity and expansion of the NixOS infrastructure, we are looking for donations to our organization.
You can donate to the NixOS foundation through SEPA bank transfers or by using Open Collective:
