Fabio joins Pascal to go deep into a listener question: How does Facebook modularise iOS applications? After discussing the state of the iOS build systems and package managers out in the wild, they turn to Buck, Facebook's monorepo build system, and how it helps developers to define clear module boundaries. One of the problems when a new module is only one new folder away are dependency graphs which look like a big ball of spaghetti. Thankfully, Buck offers some ways of taming sprawling graphs before they get out of control.
