Why Acyclic Dependency Graphs Matter in Modular iOS Projects
- Acyclic dependency graphs are essential in modular iOS projects to ensure maintainability and scalability.
- Module dependencies should form a Directed Acyclic Graph (DAG) for a healthy codebase.
- Cyclic dependencies in modules lead to issues like tight coupling, making testing, refactoring, and reusability challenging.
- To avoid cyclic dependencies, define protocols in shared modules instead of directly importing feature modules.
- Creating small modules for shared types helps in isolating definitions and preventing direct feature-to-feature dependencies.
- Hierarchically organize modules where each layer only depends on the one below it, such as App → Features → Core → Foundation.
- Encapsulate navigation logic in coordinators or routers to prevent modules from directly referencing each other.
- Modular architecture offers benefits when applied with discipline, emphasizing the importance of maintaining acyclic dependencies between modules.
- Analyzing module graphs, identifying cycles, and refactoring using the discussed strategies is crucial for project scalability and maintainability.
- Maintaining acyclic dependencies helps keep projects scalable, testable, and easy to maintain as teams and codebases grow.
- Adhering to these principles ensures a more structured and manageable modular iOS project.
