Welcome to the Getting Started Guide

Prerequisites

• Raspberry Pi
• Internet connection
• Latest Raspbian Stretch installed
  For details on how to setup your Raspberry Pi please go to raspberrypi.org

Installation

• Update Raspbian
  sudo apt-get update
• Add Swift-Lite repository
  curl -s https://packagecloud.io/install/repositories/swift-arm/swift-lite/script.deb.sh | sudo bash
• Install Swift-Lite Raspberry Pi Edition
  sudo apt-get install swift-lite-rpi
• Test swift install

swift --version
Swift version 5.0.* (swift-5.0-RELEASE)

• Test swift-lite-build install

swift-lite-build --version
swift-lite-build 3.0.*

Setup Project and Modules Directories

• Create the Projects directory
  mkdir swiftProjects
• Create the Modules directory
  mkdir swiftModules

A Quick Hello World

• Open the swiftModules directory
  cd swiftModules
• Create a file called "print.swift" and open it your favorite text editor.
  nano print.swift
• Add a simple function and save the file

func hello() {
    print("Hello World")
}

• Open the swiftProject directory
  cd swiftProjects
• Create a file called "helloWorld.swift" and open it your favorite text editor.
  nano helloWorld.swift
• Add the following code and save the file

// include:print.swift  
hello()

• The first line adds print.swift as a dependency and the second calls the hello() function from the print.swift module.
• Next build the project using the --test flag
  swift-lite-build helloWorld.swift --test
  You should see the following result

| Processing helloWorld.swift...
|
| Scanning project for modules and libraries
|  - Adding module - print.swift
|
| Generating build command
| Starting Build Process
| Build Finished
| run ./helloWorld.swapp to execute app
|
| <=-------------------------=>
|           Testing           
|
| Hello World

You are now set up and ready to code with Swift on your Raspberry Pi!
