Swift Build is a high-level build system built on llbuild with strong support for building Swift code. It serves as the build engine behind Xcode, Swift Playgrounds, and Swift Package Manager.
Use cases
- build swift packages with a faster build system
- replace the default llbuild backend in SwiftPM
- customize or extend the Xcode build system
- debug build system behavior in xcodebuild
- contribute to Apple's Swift toolchain build infrastructure
When to choose
- you're building Swift tooling or want to integrate a Swift-native build engine
- you want to test or modify the build system used by Xcode or SwiftPM
- you need programmatic control over Swift builds
When to avoid
- you just need a general-purpose cross-language build system like CMake or Bazel
- your project doesn't involve Swift or Apple platform tooling
