108 PointsI am not clear with init and self concepts.
truct RGBColor { let red: Double let green: Double let blue: Double let alpha: Double
let description: String
init() {
red = 86.0
green = 191.0
blue = 131.0
alpha = 1.0
description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
}
var color = RGBColor()
This is what the code I have written, do I have to make any changes
struct RGBColor {
let red: Double
let green: Double
let blue: Double
let alpha: Double
let description: String
init() {
red = 86.0
green = 191.0
blue = 131.0
alpha = 1.0
description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
}

6,885 PointsDoing it this way will work, BUT you lose the dynamic nature of the code, the values are stored and will always be that way since you have them in the init, and also they are constants so you can't change them ever.
Try this out:
struct RGBColor {
var red: Double
var green: Double
var blue: Double
var alpha: Double
let description: String
init(colorForRed:Double,colorForGreen:Double,colorForBlue:Double,cantForgetAlpha:Double) {
self.red = colorForRed
self.green = colorForGreen
self.blue = colorForBlue
self.alpha = cantForgetAlpha
description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
}
You can change the value all you want now.
