4,725 PointsHaving trouble with this challenge
When I wrote this in Xcode it worked fine, but the Treehouse code challenge tells me that it's wrong and to check the output for errors, but I don't see any errors. What am I doing wrong?
struct RGBColor {
let red: Double
let green: Double
let blue: Double
let alpha: Double
let description: String
// Add your code below
init(r: Double, g: Double, b: Double, a: Double, d: String) {
self.red = r
self.green = g
self.blue = b
self.alpha = a
self.description = "red: \(red), green: \(green), blue \(blue), alpha: \(alpha)"
}
func colorString() -> String {
let description = "red: \(red), green: \(green), blue \(blue), alpha: \(alpha)"
return description
}
}
let color1 = RGBColor(r: 86.0, g: 191.0, b: 131.0, a: 1.0, d: "")
let colorDescription = color1.colorString()

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)"
}
}

4,725 PointsThanks! I was forgetting the self. in the description when using string interpolation.
