WebIOPi

WebIOPiSwift is a Swift 3 library that wraps the WebIOPi REST API in a nice Swift package. It makes communicating with the GPIO pins on your Raspberry Pi from Swift code simple.

Example

let pi = WebIOPi(host: "http://raspberrypi.local:8000")
pi.GPIO.setFunction(.out, pin: 3) { status in
  if status == .ok {
    pi.GPIO.setValue(.on, pin: 3) { status in
      if status == .ok {
        print("Pin 3 is now outputting a HIGH signal.")
      }
    }
  }
}

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

A Raspberry Pi running WebIOPi.

Installation

WebIOPi is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "WebIOPi"
