How do you initialize description?

I'm trying to initialize the description. Where am I going wrong?

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

Without giving too much information so you can try it again on your own -> Your description constant is not a complete string. Check online for String Interpolation, it's quite easy to learn
