Unsure of what is incorrect

I'm guessing it has something to do with my init?

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

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

When you are creating an instance of some object it is really important you do that after closing } of a class. Not within.

correct code is:

class Shape {
    var numberOfSides: Int

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

let someShape = Shape(numberOfSides: 4)

Also, numberOfSides in init method is your parameter. When you want to assign this parameter to some variable or a constant in your class you should first write your variable or a constant like self.numberOfSides = and here you put that name within (...) in your init method. That argument, in this example some number, an integer will be applied to numberOfSides
