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.

## Installation

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, then install sourcekit-lsp from source, 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
