I have published a Swift Ros client implementation on Github at GitHub - tgu/RosSwift: ROS Robotic Operating System - Swift implementation of core client libraries and rosmaster. Based on roscpp.
Hi Thomas, that is very interesting implementation. I would like to interview you for the ROS Developers Podcast so you can share with the audience about its development, usage, maintenance, applications, etc. Please if you are interested contact me on (rtellez@theconstructsim.com)
