why is my code refusing to accept the 'super.init' call???

class Product { var title: String var price: Double

init(tit: String, pri: Double) { self.title = tit self.price = pri }

func discountedPrice(percentage: Double) -> Double { return price - (price * percentage / 100) } }

enum Size { case Small, Medium, Large init() { self = .Small } }

class Clothing: Product { var size = Size()

let designer: String init(tit: String, pri: Double, designer: String) { self.designer = designer super.init(tit: title, pri: price) }

this is my code. but an error is coming up on the last line ("super.init(tit: title, pri: price)") saying "Use of property 'title' in base object before super.init initialises it".

I have followed every step taken by Amit in the video and can't work it out because I have initialised it in my base class.

Any help would be much appreciated.

I've just checked your code and the problem is that in the initializer of your base class you are not passing in the proper variables to the superclasses' constructor:

    init(tit: String, pri: Double, designer: String) {
        self.designer = designer
        // Pass the tit and pri values to the super classes constructor
        super.init(tit: tit, pri: pri)
    }

Hence the error on why the title property was not being set in the super class.
