This is a communication and control library for iOS-based devices. For example, with this library you could program an application on Solaris which would control iOS devices or be able to transfer data to and from them, or do pedestrian things like load your own certificates into the target iOS device's store...
You can do this without this library. On iOS you could install an app like Charles Proxy, and install their cert to intercept traffic. Or you could proxy all traffic through your computer. Most apps does use certificate pinning today, but many still don't. I recently used this technique to reverse engineer a video streaming app
