what is wrong? i did not understand the question. what is the procedure to create an instance?

Initializing is the process of giving an object all it's properties an initial value. What do I mean by this ?

Let's say we want to create an object, in order for us to be able to create this object we need a "blue print", which sets the requirements for this object. This "blue print" we are going to call it a class.

Let's create a class that when fully initialized it will create a "Car", and this car will be the instance.

Example:

Here we have a class called AutoFactory, and this class has 3 properties that are optional they do not have any initial values other than "nil". As you can see the class has no initializer, so we can't give those properties any values at all so we won't be able to create an instance of this class.

class AutoFactory {

    // Properties
    let model: String?
    let color: String?
    let doors: Int?
}

let car = AutoFactory() // No initializer, so it won't create an instance.

Let's give this class an initializer:

class AutoFactory {

    // Properties
    let model: String?
    let color: String?
    let doors: Int?

    // Initializer
    init(model: String, color: String, doors: Int){
        self.model = model
        self.color = color
        self.doors = doors
    }

}

// Now we have an initializer and we can give those properties
// an initial value, and this will create an instance of the class. 
let fordFiesta = AutoFactory(model: "Fiesta", color: "White", doors: 4)

// You can access these properties with the dot notation.
fordFiesta.color // Will print white
fordFiesta.doors // Will print 4

Hope this helps you.

Hello:

So, the challenge wants you to create a class. After creating the class, you will need to create an instance of it.

Let's start by creating a class and providing it with an initializer.

class Shape {

    // Property
    var numberOfSides: Int?

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

}

The initializer is what gives properties their values.

After you have created the class, then you can have an instance of it.

// Instance of Shape. 
let square = Shape(numberOfSides: 4)

Good luck, if you don't understand please let me know.

no problem at all. yes i do if you don't mind please. i do not understand the initialiser concept. i feel like its useless.

// This is the code that I used, but unfortunately it will not compile however I'm pretty sure that it is correct

class Shape {
    var numberOfSides: Int

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

    }
let someShape = Shape(numberOfSides: 3)
}
