iOS Object-Oriented Swift Inheritance Convenience Initializers

Is it wrong way ?

Why we should use convenience init. to add default values , where we can do in such way

My way:

class Clothing: Product { var size = Size() let designer: String

init(title: String = "Clothing Item", price: Double = 99, designer: String = "Calvin Klein") {
    self.designer = designer
    super.init(title: title, price: price)
}

override func discountedPrice (_ percentage: Double = 10.0) -> Double {
    return super.discountedPrice(percentage)
}

In video:

class Clothing: Product { var size = Size() let designer: String

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

convenience init (title: String) {
    self.init(title: title, price: 99, designer: "Calvin Klein")
}

override func discountedPrice (_ percentage: Double = 10.0) -> Double {
    return super.discountedPrice(percentage)
}

So we can have same result without convenience init. ?

Thank you
