According to Wikipedia:

Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. and the open-source community. First released in 2014, Swift was developed as a replacement for Apple's earlier programming language Objective-C, as Objective-C had been largely unchanged since the early 1980s and lacked modern language features.

Running Swift-language builds and doing Swift development is possible on Linux.


Install swift-binAUR for the released version, which is a repackaged Fedora binary, or swift-languageAUR for a native build from source.

Use swift-language-gitAUR for the development version.

For code completion the sourcekit language server protocol, sourcekit-lsp is available, e.g. as plugin to visual studio code, code. See below.

Editing and code completion

Install code, nodejs and make sure that a Swift toolchain providing sourcekit-lsp (e.g. swift-languageAUR or swift-binAUR) is installed.

$ git clone git@github.com:swift-server/vscode-swift.git
$ cd vscode-swift
$ npm install
$ npm run dev-package
$ code --install-extension swift-lang-*-dev.vsix
