Help. Please!!!

My specific question is below. But I need some serious feedback. I am EXTREMELY frustrated trying to learn this. I have the syntax memorized pretty much, but what to do with it is a constant struggle. I often find myself coming here because of lack of detail in questions. I get the final conclusion, but there are probably several ways to solve this...

classes.swift
// Enter your code below


class Shape {

var numberOfSides: Int


init//(What values do I put here? I was never told what to put...) 
{

definition = "This is a definition I guess? No specifics here? So I can write whatever right?"
}
self. // What do I Put here???
let someShape = // Assign "It," what is "It?"
}

Ryan,

You are thinking along the right lines. Take a look at your code modified below with my comments inline.

// Enter your code below
class Shape {
    var numberOfSides: Int  // You did right with the property here.

    init(numberOfSides sides: Int) {  // Here we take in the numberOfSides when we initialize the object.
        // Note that I am using an external parameter name of numberOfSides but refer to it as sides inside my code.
        self.numberOfSides = sides  // Here I am setting that property for my object to be what I passed in.
    }
} // We close the class definition now and declare the object instance below in the global scope.

let someShape = Shape(numberOfSides: 4)  // Here I am initializing my Shape object passing in the int 4 for sides.

I hope this helps clear it up for you. You are doing a great job. Keep up the good work. It does get easier, I promise. :)
