Table of ContentsClose


1. Description

This layer adds support for Apple's Swift programming language, used as a general purpose scripting language.

1.1. Features:

  • Syntax highlighting with swift-mode
  • Indentation
  • Code navigation using imenu (built-in)
  • Automatic syntax checking with flycheck (available with the syntax-checking layer)

2. Install

First check that you are able to run this from the command line:

On macOS:

xcrun swift

Then to use this configuration layer, add it to your ~/.spacemacs. You will need to add swift to the existing dotspacemacs-configuration-layers list in this file.

3. Usage information

Unless configured by the user, the REPL will be invoked using the command xcrun swift. You can launch the REPL using the key binding SPC m s s (or C-c C-z). The universal prefix SPC u (C-u) may be used to modify command invocation.

4. Key bindings
