Init Method

Would be very glad if someone could help me with this code :)

structs.swift 
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 = 10.5
        self.green = 12.3
        self.blue = 5.2
        self.alpha = 2.5

        self.description = "red:\(self.red), green:\(self.green), blue:\(self.blue), alpha:\(self.alpha)"
}
let callInstance = RGBColor()
