3,859 PointsIs there an issue with string interpolation in the web-based editor?
I am stuck on this code challenge. I have my 'init' method here, which is compiling for me fine, locally in Xcode, but just says 'your code won't compile' on the web. It tells me there will be an error message but there is not.
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){
self.red = r
self.green = g
self.blue = b
self.alpha = a
self.description = "red: \(r), green: \(g), blue: \(b), alpha: \(a)"
}
}

You've pretty much got it, you're just using the incorrect variable names. I'm not 100% sure if it is, in fact, a syntax error (I don't do much in iOS), but I know that using single character variable names is never a good idea. So, while the structure is correct, the code checker does not like the single characters.
If you just rename the variables to follow Swift Naming Conventions
, the code will pass.
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)"
}
}
Keep Coding! :)
