## Description{% #description %}

This rule enforces consistent naming conventions for function names within Apex classes. Functions should follow specific naming patterns, such as starting with a lowercase letter and using camelCase formatting. Adhering to these conventions improves code readability and maintainability across development teams.

To comply with this rule, always name your functions starting with a lowercase letter and use camelCase for multiple words, for example: `myFunction`. Avoid capitalizing the first letter or using underscores. By following these best practices, your code will be cleaner, more professional, and easier to navigate.
