HomeKitBridge
HomeKit Bridge is a project that allows app developers test their HomeKit app with real hardware using Mac as a relay to communicate with accessory that doesn't support HomeKit protocol.
This project uses Apple's private framework "HAPAccessoryKit" which comes with HomeKit Accessory Simulator.
You will need to put HomeKit Accessory Simulator.app under /Applications/ to build this project. (It comes with Hardware IO Tools which you can find from here)
Currently the project only supports Philips Hue Light.
Here is a video demo.
