How am I getting compiler errors on treehousebut xcode runs this code without issue??

Here's my 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() {
self.red = 86.0
self.green = 191.0
self.blue = 131.0
self.alpha = 1.0
self.description = "red:\(red), green:\(green), blue:\(blue), alpha:\(alpha)"
}


}

You do not need to assign the values that they state in the challenge

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)")
    }
}

thanks. When got this error message "Make sure you're not using the memberwise initializer provided by default" I thought that meant the object shouldn't be accepting any argument value passed through it... Not sure I understand what memberwise means exactly.

Are there any examples of a NON-memberwise initializers anyone could offer, so I can understand by contrasting?
