Diego Freniche gave a presentation on managing third party libraries in iOS projects using CocoaPods. He explained the traditional approach of manually adding libraries to projects can become messy and difficult to manage. CocoaPods provides a better solution by allowing libraries to be specified in a Podfile and automatically downloading, installing and integrating them. It also handles dependencies and updating libraries. Diego demonstrated how to set up a CocoaPods project, add public and private third party libraries to the Podfile, install the libraries and clean up projects. CocoaPods provides benefits over traditional library management by keeping projects organized and libraries up to date.
