Class Initializer

Hello, Im having problems with this exercise, can someone explain how to do it correctly and how to initialize a class? Thank you

classes.swift
// Enter your code below

class Shape {
 var numberOfSides: Int

 init(numberOfSides: Int) {
 self.numberOfSides = numberOfSides
 }
}

let someShape = Shape()

Almost there! The only thing is, now that you have a custom initializer that expects a parameter, you also need to pass the value for this parameter. For example, like this:

let someShape = Shape(numberOfSides: 4)

Hope that helps :)

Thanks alot!!
