IDK how to create an instance with a class, it isn't showing values even after "initialization"

objects.swift
//Classes
class Shape {
    let numberOfSides: Int

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

let someShape: Shape

To make a instance of a class, you basically "call" the class. It may seem like you are "calling" the class, but really behind the scenes Swift is actually calling the class's init method.

Here's how you would make a instance of the Shape class:

let someShape: Shape = Shape(numberOfSides: 4)

I hope this helps. ~Alex
