Challenge Task 1

Can someone please explain what I'm doing wrong here.. I keep getting a compile error. Something to do with assigning a property to itself. Thanks

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

    init(sides numberOfSide: Int) {
    self.numberOfSides = numberOfSides
    }
}
let someShape = Shape(sides: 3)

Hey Kyle,

you almost got it right! The only problem is a typo: You called the parameter in the init method numberOfSide instead of numberOfSides . If you fix this it should work.

I hope that helps! :)
