Swift

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
