Here’s an example of swift class for a rectangle that has an initializer and optional default values. import Foundationclass Rectangle: Codable { var name:String var length:Int var width:Int init(name:String = “”, length:Int = 4, width:Int = 2) { self.name = name self.length = length self.width = width }}This rectangle will have an area of 8 by default: r = Rectangle()print(r.length * r.width) // => 8but if we define the width to be 4, we will have a square with an area of 16 s = Rectangle(width: 4)print(s.length * s.width) // => 16This also allows you to be able to instantiate your class without defining all values and not have it blow up on you.
