add a method to a class in swift

To add a method to a class in Swift, you can define a function within the class definition. This function can be an instance method, which means it operates on an instance of the class.

Here's an example:

main.swift
class MyClass {
    func myMethod() {
        // method code goes here
    }
}

In this example, we've defined a class called MyClass. Within the class definition, we've added an instance method called myMethod(). This method doesn't have any parameters or return values, but you can modify it to take arguments and return values as needed.

To use this method, you would first create an instance of MyClass, and then call the method on that instance:

main.swift
let myObject = MyClass()
myObject.myMethod()

This code creates a new instance of MyClass and assigns it to the myObject constant. Then, it calls the myMethod() method on that instance.
