According to [[Wikipedia:Swift (programming language)|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.

== Installation ==

[[Install]] {{AUR|swift-bin}} for the released version, which is a repackaged Fedora binary, or {{AUR|swift-language}} for a native build from source.

Use {{AUR|swift-language-git}} for the development version.

For code completion the sourcekit language server protocol, [https://github.com/apple/sourcekit-lsp sourcekit-lsp] is available, e.g. as plugin to visual studio code, {{Pkg|code}}. See below.

=== Editing and code completion ===

[[Install]] {{Pkg|code}}, then install sourcekit-lsp from source, {{Pkg|nodejs}} is needed.

 $ git clone git@github.com:apple/sourcekit-lsp.git
 $ cd Editors/vscode
 $ npm run createDevPackage
 $ code --install-extension out/sourcekit-lsp-vscode-dev.vsix

== Hello world ==

The Swift package manager allows to create example programs.

 $ swift package init --type executable
 $ swift run

For a library:

 $ swift package init
 $ swift build

== Read eval print loop, REPL ==

For details on the swift REPL, see [https://swift.org/getting-started/#using-the-repl here].
