Installing Swift

To kickstart your journey, install Swift to begin using it on macOS, Linux, or Windows.

Tip: To test that you have Swift installed, run swift --version from your shell or terminal app.

Swift comes bundled with the Swift Package Manager (SwiftPM) that manages the distribution of Swift code. It allows easy importing of other Swift packages into your applications and libraries, making it a valuable tool for any Swift developer.

Swift is covered by the Apache License, Version 2.0.
