Episode 14 introduces Adam, the first dedicated iOS developer that Mihaela and Pascal have hosted on the podcast. Adam created ComponentKit, an iOS open-source framework inspired by React, and he joins this episode to tell the story of how the framework was built and adopted. Adam shares some insight on API design considerations, how to build frameworks around scalability and correctness and what the current challenges of working on the Facebook iOS apps are. Before you hear all about this, Daniel gives a special bite-sized intro to Spectrum, an open-source image processing library for Android and iOS, so this episode is one that can’t be missed!
