Getting Error: Extra argument 'title' in call. Near end of video

On the last line of my code I am getting the error: Extra argument 'title' in call. I have inherited the supers init and added the designer into it as well but it does not want to work out.

when I type in : var t-shirt = Clothing it auto completed to (designer: String)

Here is my code:

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

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

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

}

var tshirt = Clothing(title: "Vintage", price: 400.00, designer: "Prada")

So it appears there is a change in the init when a super.init is used change the init to include the parameters of the class

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

}

var tshirt = Clothing(title: "Vintage", price: 49.99, designer: "Prada")
