what am i doing wrong with this instance

Let's get in some practice creating a class. Declare a class named Shape with a variable property named numberOfSides of type Int.

Remember that with classes you are required to write an initializer method.

Once you have a class definition, create an instance and assign it to a constant named someShape.

classes.swift 
// Enter your code below
class Shape {
var numberOfSides: Int

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

class Shape{
    var numberOfSides: Int

    init(numberOfSides: Int){
        self.numberOfSides = numberOfSides
    }
}
let someShape = Shape(numberOfSides: 6)

You didn't assign "self.numberOfSides = numberOfSides". Also you need to call that instance by using the class "Shape" at the end instead of "numberOfSides". The class "Shape" contains "numberOfSides" so when you calls "Shape" it recognizes it needs to call "numberOfSides". Hope this helps!
