Codedeck 
A Swift library for interfacing with an Elgato StreamDeck.
Features
- Multiplatform Support (See below)
- Hotswapping and Multiple Connected Devices Support
- Set Device Brightness
- Fill Key with Solid RGB Colors
- More Soon!
Multiplatform Support
Swift is compatible with most modern systems and this project makes an effort to keep dependencies light and not coupled to things like Cocoa/UIKit etc.
There are some extensions which, if Cocoa is available, adds extra functionality but this does not limit what you're able to do rather just makes things simpler!
Usage
Creating a StreamDeck
A StreamDeck currently requires a HIDDevice to be created. This is a thin
wrapper around the IOHIDDevice available in Apple's IOKit.
This library provides a device monitoring solution which informs of you when certain devices are connected/disconnected from the system. This allows you to hotswap StreamDeck devices as well as connect to multiple at once!
// 1. Create a device monitor and store a reference to it in your application
var monitor: HIDDeviceMonitor = {
return HIDDeviceMonitor(streamDeckProducts: [ .streamDeck ])
}()
// 2. Create a delegate class within your application
extension SomeClass: HIDDeviceMonitorDelegate {
func HIDDeviceAdded(device: HIDDevice) {
// ...
}
func HIDDeviceRemoved(device: HIDDevice) {
// ...
}
func HIDDeviceError(error: Error) {
// ...
}
}
// 3. Start monitoring for existing and new devices
monitor.startMonitoring(delegate: ...)
// 4. When you have access to a "HIDDevice" initialize a "StreamDeck" with it
