Compiler errors are not showing

Compiler said my code is wrong but there's no error showing in the preview

structs.swift 
struct RGBColor {
  let red: Double
  let green: Double
  let blue: Double
  let alpha: Double

  let description: String

  // Add your code below
  init() {
    self.red = 86.0
    self.green = 191.0
    self.blue = 131.0
    self.alpha = 1.0

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

You just need to pass in the values of red, green, blue and alpha 

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)"
  }
