2,395 PointsHey community, my code here doesn't pass as correct, can I have some help?
Hey guys my code; specifically the self.description = "(red: self.red, green: self.green, blue: self.blue, alpha: self.alpha)" } passes on Xcode but is stated as incorrect according to treehouse! Any ideas why? cheers
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) {
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)" }
}
//This passes on xcode but is not accepted as correct in the challenge!

iOS Development Techdegree Graduate 15,223 PointsHey Jordan,
You code is correct which is why it is working in Xcode. The problem you have here is a requirements issue.
The requirements state:
the description property should look like this: "red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0"
currently if you were to print the description to the console it wouldn't look like what the requirements are requesting.
Consider the code below
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)"
}
}

2,395 PointsYes thats what I used to pass, but I still don't understand the difference? isn't that the interpolated version of the same thing I typed?
