12,885 PointsInit is a function which you need to define using parameters. Your mistake is that you keep entering values into it.
This is it:
// we define a function named init which initialises all the attributes of the struct, with the values which are passed to it
init(red : Double, green : Double, blue : Double, alpha : Double){
self.red = red
self.green = green
self.blue = blue
self.allha = alpha
self.description= "red: /(red), green: /(green), blue: /(blue), alpha: /(alpha)"
}
After we defined this init function we can create a RGBColor struct using:
let someColor = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
, they don't ask you to do this in the assignment, but this demonstrates how the struct can be used after it is properly defined.

12,885 Points // Add your code below
init(red : Double, green : Double, blue : Double, alpha : Double){
self.red = red
//do the same as I did with red for the green, blue and alpha
//then put all the values in the description constant
}

I tried that and I still could not get it to work
