iOS Object-Oriented Swift Complex Data Structures Custom Initializers

This seems to work fine in Xcode? Structs in Swift...

I tried var.rgbColor among other variations, Xcode prefers _ anyway nothing seems to be correct.

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
        self.description = "red: \(self.red), green: \(self.green), blue:\(self.blue), alpha:\(self.alpha)"
        _ = RGBColor  (red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)

    }
}

Your self.description line seems correct to me. I tried it as well and couldn't pass the test, so this may be a problem with the test itself and not your code. Note though that you don't want the last line where you call _ = RGBColor within the init method. If you wanted to create an instance, that would be something you do outside the struct.

There is nothing wrong with the test you have two small typos.

First, Shade is right in order to create and instance you would do that outside the struct.

Second, you need to make it look exactly like the example in the answer. You are missing two spaces it should be:

self.description = "red: (self.red), green: (self.green), blue:\ (self.blue), alpha:\ (self.alpha)" notice the spaces after blue:\ and alpha:\

You have: self.description = "red: (self.red), green: (self.green), blue:(self.blue), alpha:(self.alpha)"
