iOS Infrastructure
summary
Facebook iOS work is built as layered libraries and independent modules register URLs so Newsfeed, Timeline and Messaging navigate via URL routing; code lives in an Xcode workspace with one config file for consistent builds. Reusable libraries include FBFoundation, FBUKit, FBDataModel and FBAppKit; tools include mo_generator for Core Data classes, FBManagedObjectObserver to batch updates, FBTracer for timing, clang-based lint in fabricator, and snapshot unit tests that caught UI regressions. Runtime tooling adds a tunable watchdog timer and employee-only shake reports; deployment uses enterprise builds plus a nag to force updates.
