Even though we are inheriting properties from our superclass, you still need to declare them in your subclass initializer:

Error; we're pulling in title from our superclass initializer but not using them in our subclass initializer:

init(designer: String) {
    self.designer = designer
    super.init(title: title, price: price)
}

There we go:

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