Swift Code Refactoring: Enhance with Elegance-Swift code refactoring tool

Example

A complex function that handles user authentication with nested if-else blocks and hardcoded error messages can be simplified using Swift's `guard` statement and error handling through `throws`.

Scenario

In a project where authentication logic is scattered throughout the code, refactoring will centralize the logic in one place. The introduction of helper functions will make the code more readable, shorter, and easier to debug.

Example

Refactoring a loop that inefficiently iterates over arrays multiple times into a single pass using a `reduce` function or by using Swift’s efficient `map` or `filter` higher-order functions.

Scenario

In a data-heavy app where multiple collections are processed, such as a financial or real-time analytics app, optimizing the algorithms by reducing redundant calculations can drastically improve the performance.

Example

Breaking down a large monolithic view controller into smaller, reusable components by applying the Model-View-Controller (MVC) or Model-View-ViewModel (MVVM) patterns, where each part has a clear responsibility.

Scenario

In a large-scale iOS app with dozens of views, modularization helps in reducing code duplication, making each component easier to test, extend, and maintain. It also allows new developers to jump in and understand specific sections of the app without needing to grasp the entire codebase.
