Modularization techniques from monolithic to multi-packages app
summary
Shows how a monolithic Swift app is split into layered and feature packages using Swift Package Manager, moving through three phases (layer extraction, feature packages, decoupled navigation). Demonstrates multiple targets per package, a working mini app that imports only the movie feature, and a simple router/mediator to eliminate cyclic dependencies. Claims per-feature builds are far faster than full-app builds, warns about too many modules increasing launch size, and suggests static libs or tighter boundaries when modules grow.
