Because scaling up your engineering team is never about hiring more people. iOS Engineers that being in-charge of taking their codebase to the next level must ever heard about modularization. But how to start one? What are the common pitfalls? In this session I would like to talk about journey on having our first hand experience regarding why some teams that experimenting to do modularization don't feel the benefit of doing it and how to solve the rising problems after doing modularization in iOS. After the session, attendees are expected to get something about tips and knowing the pitfalls when doing modularization for their first time in iOS codebase.
