Description

All variables of type IBOutlet should be set as private. IBOutlet variables are typically used in Swift to connect the UI elements from the storyboard to the code. Making these variables private enhances encapsulation and data hiding, which are fundamental principles of object-oriented programming.

Non-Compliant Code Examples
