Hey neat, it's a nice open source OSC library for Objective-C.

From your friends at Figure 53.

For convenience, we've included a few public domain source files from CocoaAsyncSocket. But appropriate thanks, kudos, and curiosity about that code should be directed to the source.

• F53OSC must be compiled with ARC.
• You must link against Security.framework and CFNetwork.framework.
• F53OSC requires Xcode 6.3 or later and a deployment target of macOS 10.9+ or iOS 8.4+.

Inluded is a small demo app "F53OSC Monitor", which logs OSC messages sent to it via port 9999 and displays some basic stats about incoming traffic.
