Raspberry Pi Coding in Swift: Traffic Lights itnext.io

As long time readers know, I’ve written a series of articles each describing how to get up and running with controlling the Raspberry Pi GPIO pins using different programming languages. In each article, I use the same example of a set of traffic light LEDs so that you can compare and contrast the different language implementations. With the possible exception of a future ARM assembler post (steep learning curve for me there — but I do like working at such a low level!), I thought I’d run out of languages to try. Recently, I stumbled across this blog post which describes how to install Swift on the Pi so I thought I’d try it out…
