[Help!] How to write initialiser method without a 2nd property?

1) The example in the previous video used the second property in the init method, but the example doesn't have this, so Im not sure how to write it.

2) Also, Im a little confused as to wether a tuple is required for an init method.

3)Finally Im not sure if my instance is correctly assigned

Would appreciate any help!

classes.swift 
// Enter your code below
class Shape {
    var numberOfSides: Int  = 3
    let x: Int
    let y: Int
    init(numberOfSides: Int) {
       self.numberOfSides = Int(x: x, y: y) //Not sure what goes in here?
    }

  } 

let someShape = Shape(x: Int, y: Int) // Not sure whats wrong with my Arguement?

There's no need for x and y. Shape objects just have a number of sides:

class Shape {
    var numberOfSides: Int  = 3

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

  let someShape = Shape(numberOfSides: 3)
