what is wrong

?

structs.swift 
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 = 86.0
        self.green = 191.0
        self.blue = 131.0
        self.alpha = 1.0

    }
    func yaay(description a:String) -> String {
        let a = "\(RGBColor)"
        return a
    }

}

let kiwi = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
let jkj = kiwi.yaay(description: "\(RGBColor)")

I just finished this one. You don't need to create a function for the description, you just define it as another initializer 

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