struct RGBColor {
let red: Double
let green: Double
let blue: Double
let alpha: Double
let description: String
// Add your code below
init (red : Int , green: Int , blue : Int , alpha: Int , description: String){
self.red = red
self.green = green
self.blue = blue
self.alpha = alpha
self.description = "red: \(red) ,green: \(green) ,blue: \(blue) , alpha:\(alpha)"
}
func getcolor (red : Double , green: Double , blue: Double , alpha: Double){
return "red: \(red) ,green: \(green) ,blue: \(blue) , alpha:\(alpha)"
}
}
let acolor = getcolor (red : 86.0 , green:191.0, blue:131.0, alpha: 1.0)

15,959 PointsHi, You do not need to include the description property in the initializer function. Here is how I would create the RGBColor struct. Notice that the init takes Double values and not Int
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
description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
}
By passing in all the Double values you can create a string and assign it to the description property. That way you automatically create a value for the description property every time you initialize a new RGBColor object.
You can access the description property the following way now:
let someColor = RGB(red: 86.0, green:131.0, blue: 91.0, alpha:0.8)
let someDescription = someColor.description
//someDescription will be "red: 86.0, green: 131.0, blue: 91.0, alpha: 0.8"
