In what situations does a static method call occur in programming languages?

Static method calls occur when a method is called through the class name rather than an instance of the object. In iOS (Swift or Objective-C), this usually refers to methods declared as static or class methods.

Situations where static calls are used:

• When the method does not depend on the state of a specific object but performs a general function.
• To create factory methods that return instances of the class.
• To access utility functions, such as mathematical operations.

Example in Swift:

class MathUtils {
    static func square(_ number: Int) -> Int {
        return number * number
    }
}

let result = MathUtils.square(5) // static method call without creating an object
