Modularizing a monolithic iOS app
WHAT IT TESTS: incremental modularization strategy. OUTLINE: extract low-dependency, high-reuse leaf code first behind clear interfaces, enforce boundaries, iterate inward.
WHAT IT TESTS: pragmatic, dependency-aware decomposition rather than a risky rewrite. ANSWER OUTLINE: map the dependency graph, then extract a stable leaf module first such as a design system, core models, or networking that many features depend on but which depends on little; define a clean public interface, move code, and enforce the boundary so the module compiles in isolation. Iterate, peeling layers and gaining faster incremental builds and clearer ownership.
