iOS Object-Oriented Swift Complex Data Structures Custom Initializers

Code could not be compiled

This code for the initializer task ran in my Xcode debugger, but not in the Treehouse console. Would be great to know whether a. there is indeed a compiling issue, and b. if it is the correct code for the task.

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

  let description: String

  // Add your code below
  init (red: Double, green: Double, blue: Double, alpha: Double) {
       self.red = red
        self.green = green
        self.blue = blue
        self.alpha = alpha

        description = "red:\(red), green:\(green), blue:\(blue), alpha:\(alpha)"
}

Almost! Two small issues:

You were missing a bracket to close off your init method. You were missing a space between Red: (value) in the interpolated string.

code:

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

  let description: String

  // Add your code below
  init (red: Double, green: Double, blue: Double, alpha: Double) {
       self.red = red
        self.green = green
        self.blue = blue
        self.alpha = alpha

        self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
  }
}
