I have my class and variable, I think i didn't write out my initializer correctly.
// Enter your code below
class Shape {
var numberOfSides: Int
init(){
let someShape: numberOfSides
}
}

Good start, but you're spot on, your init method is a little bit off.
You want to add a parameter to your init method so that you can customise the number of sides that any instance of shape will have. Using the value that is passed into this parameter, you need to assign it to the numberOfSides variable that you have created within your class.
Once you have created your init method, you then need to create an instance of shape and assign it to a new constant named newShape. Whilst doing this, you will have to pass in an integer value in order to satisfy the init method you have just created.
class Person
{
var age: Int
init(age: Int)
{
self.age = age
}
}
let somePerson = Person(age: 25)
I've provided a very similar example above that will hopefully illustrate what I've described. I hope this helps, let me know if you need any further pointers!
