+#+TITLE: Swift contribution layer for Spacemacs

+
+* Description
+This layer adds support for Apple's Swift programming language, used as a
+general purpose scripting language.
+
+It relies on the [[https://github.com/chrisbarrett/swift-mode][swift-mode]] major-mode* for Emacs 24.4 or later, to provide the
+following features:
+
+- Syntax highlighting
+- Indentation
+- Code navigation using ~imenu~ (built-in)
+- Automatic syntax checking with ~flycheck~ (available with the
+  ~syntax-checking~ layer)
+
+* Install
+To be able to use this layer you should be able to run this from the
+command line:
+
+On OS X:
+#+BEGIN_SRC sh
+  xcrun swift 
+#+END_SRC
+
+* Usage information
+
+Unless configured by the user, the REPL will be invoked using the command ~xcrun
+swift~.
+
+You can launch the REPL using the keybinding ~SPC m s s~ (or ~C-c C-z~).
+
+The universal prefix ~SPC u~ (~C-u~) may be used to modify command invocation.
+
+* Key bindings
+
+** swift-mode
+
+| Emacs             | Evil                  | Description            |
+|-------------------+-----------------------+------------------------|
+| [~C-u~] ~C-c C-z~ | [~SPC u~] ~SPC m s s~ | swift-mode-run-repl    |
+| ~C-c C-f~         | ~SPC m s b~           | swift-mode-send-buffer |
+| ~C-c C-r~         | ~SPC m s r~           | swift-mode-send-region |
+
+Notes: 
+
+1. ~swift-mode-run-repl~ will run or switch to an existing REPL.
+2. To edit the command invocation, prefix with ~SPC u~ (or ~C-u~).
+3. Emacs key bindings in use are the those set by the package.
