[^1]: Since LLVM project doesn't provide pre-built binaries of `lld` for macOS on x86_64, it will be automatically built
from sources by the generator, which will increase its run by at least 15 minutes on recent hardware. You will also
need CMake and Ninja preinstalled (e.g. via `brew install cmake ninja`).
[^2]: Swift does not officially support Debian 11 or Debian 12 with Swift versions before 5.10.1. However, the Ubuntu 20.04/22.04 toolchains can be used with Debian 11 and 12 (respectively) since they are binary compatible.

Debian 13 is also not officially supported, but can be used with the Ubuntu 24.04 toolchain.
[^3]: These versions are technically supported but require custom commands and a Docker container to build the Swift SDK, as the generator will not download dependencies for these distributions automatically. See [issue #138](https://github.com/swiftlang/swift-sdk-generator/issues/138).
