iOS Object-Oriented Swift Complex Data Structures Custom Initializers

Object-Oriented Swift

struct RGBColor { let red:Double let green:Double let blue:Double let alpha:Double

let description:String

init(red:Double,green:Double,blue:Double,alpha:Double, description:String) {
    self.red = red
    self.green = green
    self.blue = blue
    self.alpha = alpha
    self.description = description
}

} How can we assign RGB color Object to string Description. since description is one of the stored property of the RGB Object?

structs.swift
struct RGBColor {
  let red: Double
  let green: Double
  let blue: Double
  let alpha: Double

  let description: String

  // Add your code below
}

Hi,

You must construct description in initializer using the other fields:

description = "red: (red), green: (green), blue: (blue), alpha: (alpha)";
