Darwin Swift SDK for Linux (experimental)

swift-sdk-darwin

SDKs for cross-compiling Darwin code on Linux.

Building

Prerequisites:

• macOS or Linux
• jq (brew install jq or apt install jq)

Steps:

1. Download Xcode 15.0 or higher.
   • If you're on Linux, you can unpack Xcode.xip using unxip.
2. Run ./build.sh <linux host> [developer dir].
   • linux host: You can pass any Linux host for which a darwin-tools-linux release exists. e.g. ubuntu22.04-aarch64.
   • developer dir: this should be the path to Xcode.app/Contents/Developer. On macOS, you can omit this argument to let the script infer it.

Find the output at output/*.artifactbundle.

Installing

Prerequisites:

• Linux
• Swift 5.9 toolchain (https://swift.org/download)

Steps:

1. Build a toolchain as described above.
2. Run output/*.artifactbundle/install.sh on your Linux machine.

Usage

swift build --experimental-swift-sdk ios16.0

TODO

• Make it easy to use CI (nb: we avoid distributing pre-packaged toolchains for legal reasons)
• Remove installation script once SwiftPM bugs are fixed
