What are the advantages and disadvantages of system modularization?

Dividing a system into modules allows breaking down a complex application into independent parts, each responsible for its functionality. This facilitates code maintenance and development, increases component reusability, and simplifies teamwork, as different teams can work on different modules in parallel.

Advantages:

• Improved readability and structure of the code.
• Localization of changes: modifications in one module minimally affect others.
• Increased testability: modules can be tested separately.
• Ability to reuse modules in other projects.

Disadvantages:

• Complexity in managing dependencies between modules.
• Possible increase in build and startup times due to multiple modules.
• Need for thoughtful interface design between modules.

In iOS development, modules can be implemented as separate frameworks or Swift Package Manager packages, which helps isolate code and manage dependencies.
