This document discusses how to set up Swift programming on a Raspberry Pi, including installing the Raspbian operating system, prerequisites like Clang and ICU, adding repositories to install Swift 2.2, and using the SwiftGPIO library to control GPIO pins and blink an LED as a simple example program. Requirements include a Raspberry Pi 2 Model B, microSD card, and wireless adapter.

5. Requirements
◉Raspberry Pi 2 Model B
◉8 GB microSD card
◉USB wireless adapter

6. Operation System
◉Raspbian Jessie from raspberrypi.org

7. Getting Started
◉Copy the Raspbian image on microSD card
◉Resize the Raspbian image partition
◉Setup the Internet environment

8. sudo vi /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid=”Mission”
psk=”00000000"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
auth_alg=OPEN
}

9. Prerequisites
Install clang-3.6 and libicu-dev via apt-get
wget http://repos.rcn-ee.com/debian/pool/main/r/rcn-ee-archive-keyring/
rcn-ee-archive-keyring_2015.10.22~bpo90+20151022+1_all.deb
sudo dpkg -i rcn-ee-archive-keyring_2015.10.22~bpo90+20151022+1_all.deb
echo "deb [arch=armhf] http://repos.rcn-ee.com/debian/ jessie main" | sudo
tee --append /etc/apt/sources.list
sudo apt-get update

10. Prerequisites
sudo apt-get install libicu-dev
sudo apt-get install clang-3.6
sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-3.6
100
sudo update-alternatives --install /usr/bin/clang++ clang++
/usr/bin/clang++-3.6 100

11. Install Swift 2.2
◉ Add the @iachievedit repository key
wget -qO- http://dev.iachieved.it/iachievedit.gpg.key | sudo apt-key add -
◉ Add the repository to source.list
echo "deb [arch=armhf] http://iachievedit-repos.s3.amazonaws.com/ jessie
main" | sudo tee --append /etc/apt/sources.list
◉ Install Swift 2.2
sudo apt-get update
sudo apt-get install swift-2.2

12. SwiftGPIO
◉ Manually download SwiftGPIO.swift
wget https://raw.githubusercontent.com/uraimo/SwiftyGPIO/master/Sources/
SwiftyGPIO.swift

13. SwiftGPIO
◉ Create a main.swift file and make our Raspberry Pi lighten up a LED.
import Glibc
let gpios = SwiftyGPIO.getGPIOsForBoard(.RaspberryPi2)
gpios[.P26]!.direction = .OUT
while true {
gpios[.P26]!.value = 1
}

14. SwiftGPIO
◉ Compile it
swiftc SwiftyGPIO.swift main.swift
◉ Run it
sudo ./main
