About CocoaHeads

image.png is an international group devoted to discussion of Apple's Cocoa Framework for programming on macOS and iOS. During monthly meetings, members present on their projects and offer tutorials on various programming topics.

We are the CocoaHeads Aachen Chapter, hosted by the Media Computing and Human-Computer Interaction Group at RWTH Aachen University. We get together for informal short talks and demos, have a pizza, and talk code. 

From time to time it happens that we draw prizes sponsored by supporting companies like: JetBrains, dpunkt.verlag, O'Reilly
