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

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

9,264 PointsI think your issue may just be with formatting as your code is correct and does work for me. The title and price stored properties should be on their own line or separated by ;
class Product {
let title: String
var price: Double = 0.0
init(title: String, price: Double) {
self.title = title
self.price = price
}
func discountedPrice(percentage: Double) -> Double {
return price - (price * percentage / 100)
}
}
class Furniture: Product {
let height: Double
let width: Double
let length: Double
var surfacearea: Double{
return length * width
}
init(title: String, price: Double, height: Double, width: Double, length: Double) {
self.height = height
self.width = width
self.length = length
super.init(title: title, price: price)
}
}
