What criteria indicate high-quality software code?

High-quality software code is characterized by the following criteria:

• Readability: the code should be understandable to other developers, with meaningful names for variables, functions, and classes.
• Maintainability: the code structure should allow for easy modifications and fixes.
• Modularity: the code is divided into small, independent, and reusable parts.
• Absence of duplication: repetitive code should be avoided by using functions and classes.
• Performance: the code should operate efficiently without unnecessary resource consumption.
• Error handling: proper and predictable handling of exceptions and errors.
• Testability: the code should be easily covered by unit tests.

For example, in iOS development, it is important to follow the Swift coding style, use clear names, and adhere to architectural patterns (MVC, MVVM) to facilitate support and development of the application.
