add a public method to a class in swift

To add a public method to a class in Swift, you simply need to prefix the method declaration with the public keyword. Here's an example:

main.swift
public class MyClass {
    public func myPublicMethod() {
        // Code for your method goes here
    }
}
108 chars
6 lines

In the example above, MyClass is a public class and myPublicMethod() is a public method. This means that the method can be accessed from outside the class, by other classes or modules that import this one.

If you don't add the public keyword to your method, it will be treated as an internal method, which means it can only be accessed from within the same module.
